3x+3 + 10x-4 +90 (because complementary angle add up to 90)

13x-1+90 (add 1)

13x/13=91 (divide 13 on both sides)

x=7

now you fill in 7 for x

m<K=24 and m<L=66

hope i helped

The measures of both angles are 24° and 66°.

Given:

m<K = 3x + 3

m<L = 10x-4

Note:

Complementary angles are angles whose sum equals 90 degrees.

Therefore:

[tex]m \angle K + m \angle L = 90^{o}[/tex]

Substitute

[tex](3x+3) + (10x-4) = 90[/tex]

Solve for x

[tex]3x+3 + 10x-4 = 90\\[/tex]

Add like terms

[tex]13x-1 = 90\\[/tex]

Add 1 to both sides

[tex]13x = 90 + 1\\13x = 91[/tex]

Divide both sides by 13

[tex]x= 7[/tex]

Substitute the value of x in each of the expressions of the two given complementary angles.

[tex]m\angle K = 3(7) + 3 = 21 + 3\\m\angle K = 24^{o}[/tex]

[tex]m\angle L = 10(7) - 4 = 70 - 4 \\m\angle L = 66^{o}[/tex]

Therefore, the measures of both complementary angles are: 24° and 66°.

I believe it is 30% because you can divide 200 in half to get it out of 100, and then divide 60 in half to make it even! (i’m sorry if this doesn’t make sense)

Final answer:

To calculate what percent of people like rap out of 200 who came to a fundraiser, divide the 60 people who like rap by 200 and multiply by 100, resulting in 30% of people liking rap.

Explanation:

The question asks us to calculate what percent of people like rap out of 200 kids who came to a fundraiser. To find the percentage of people who like rap, we use the basic formula for finding percentages: (Part / Whole) × 100. Here, the 'Part' is the number of people who like rap, and the 'Whole' is the total number of kids who came to the fundraiser.

Given:
Part (people who like rap) = 60
Whole (total kids at the fundraiser) = 200

Using the formula, we calculate the percentage as follows:
(60 / 200) × 100 = 0.3 × 100 = 30%.

Therefore, 30% of the people at the fundraiser like rap.

for the rectangular red paper :

w₁ = width of the red paper = 4 cm

L₁ = length of red paper = 2 w = 2 x 4 = 8 cm

A₁ = area of the red paper = L₁ w₁ = 8 x 4 = 32 cm²

for the rectangular blue paper :

w₂ = width of the blue paper = 3 cm

L₂ = length of blue paper = 7 cm

A₂ = area of the blue paper = L₂ w₂ = 7 x 3 = 21 cm²

area visible is given as

A = A₁ - A₂ = 32 cm² - 21 cm² = 11 cm²

so 11 square units of red paper will be visible on top

Let's assume

number of months =x

A high definition radio station charges $200 per year

so, we get point as (0,200)

Assume

f(x) is the total amount of charges in a year

we can see that this is linear relationship

so, we can use formula

[tex]f(x)=mx+b[/tex]

in addition to $50 per month for the first 3 months to receive its broadcast

so, m=50

we can plug it

[tex]f(x)=50x+b[/tex]

we can use point as (0,200)

[tex]200=50*0+b[/tex]

[tex]b=200[/tex]

now, we can plug it back

and we get

Answer:

We should use 4 pounds of $6 coffee and 2 pounds of $3 coffee for the blend.

Step-by-step explanation:

The blend should,

Cost = $5

Weigh = 6 pounds.

Lets take the weight of $6 coffee as [tex]x[/tex] pounds

And lets take the weight of $3 coffee as [tex]y[/tex] pounds.

Lets write an equation for the weight of the blend,

[tex]x+y=6[/tex] <---------- 1st equation.

[tex]\frac{6x+3y}{x+y} =5[/tex]

=[tex]6x+3y=5x+5y[/tex]

=[tex]x=2y[/tex] <---------- 2nd equation

We can substitute to x in 1st equation from 2nd equation,

⇒[tex]2y+y=6[/tex]

=[tex]2y+y=6[/tex]

=[tex]3y=6[/tex]

=[tex]y=2[/tex]

We can substitute y value to 2nd equation to find x,

⇒[tex]x=2y[/tex]

=[tex]x=2*2[/tex]=[tex]x=4[/tex]

Therefore, we should use 4 pounds of $6 coffee and 2 pounds of $3 coffee for the blend.

Answer:

Amount of ribbon used = [tex]73 \frac{1}{8} yards[/tex] = 73.125 yards.

Explanation:

 Number of ribbon rolls = 15

 Number of wedding basket = 10

 Length of 1 ribbon roll = [tex]5\frac{3}{8}=\frac{5*8+3}{8} =\frac{43}{8}[/tex] yards.

Total length of 15 ribbon roll = [tex]15*\frac{43}{8} =\frac{645}{8}[/tex]yards.

Length of ribbon cutting from each basket = [tex]\frac{3}{4}[/tex]yards.

Total length of ribbon cutting from 10 baskets = [tex]10*\frac{3}{4}=\frac{15}{2}[/tex] yards

Amount of ribbon used

                  [tex]=\frac{645}{8}-\frac{15}{2}=\frac{645}{8}-\frac{15*4}{2*4}=\frac{645}{8}-\frac{60}{8}\\ \\ =\frac{585}{8} =73 \frac{1}{8} yards[/tex]

Amount of ribbon used = [tex]73 \frac{1}{8} yards[/tex] = 73.125 yards.

-12(x+2)=6(-4-2x)+4x

-12x-24=-24-12x+4x

x=0

x is equal to zero. Distribute The -12 to x and 2. Then distribute the 6 to -4 and -2.

That gives you -12-24=-24-12x+4x

combining like terms gives you -12-24=24-8x

next you should get x by itself.  that gives you 0 as the final answer

Obviously, if he were to only maximize his income he would put all money on the higher interest. But to reduce the risk he will balance the investment. He will put a fraction a (between 0 and 1) of the 710000 on 1% and the rest (1-a) on the 4.5%.  Both interests together must then satisfy to add up to 18000.

So written as an equation:

[tex]710000\cdot a\cdot 0.01 + 710000\cdot(1-a)\cdot 0.045 = 18000[/tex]

I am not going to solve step by step assuming you can solve for a (if not let me know) but the solution is

Since it is true that 9=9, the answer x=2 works.

As equations get more complex it is important to use properties of equality to isolate the variable and solve the equation.

Here are the properties of equality you need to isolate terms and solve equations.

The Subtraction Property of Equality is used when you have an equation with addition in it. It states that you can subtract the same quantity from both sides of the equation without changing the equality.

The Addition Property of Equality is used when you have an equation with subtraction in it. It states that you can add the same quantity to both sides of the equation without changing the equality.

The Division Property of Equality is used when you have an equation with a variable multiplied by a number. It states that you can divide both sides of an equation by the same quantity (as long as that quantity is not equal to zero) without changing the equality.

The Multiplication Property of Equality is used when you have an equation with a variable divided by a number. It states that you can multiply both sides of an equation by the same quantity without changing the equality.

Let’s look at an example and use properties of equality to isolate the variable and solve the equation.

To find out how many cans of food were collected in the second week, subtract the number of cans collected in the first week from the total number of cans collected in two weeks. The inequality representing the problem is c + 145 > 380. Solving the inequality, we find that more than 235 cans were collected in the second week.

To find out how many cans of food were collected in the second week, we can subtract the number of cans collected in the first week from the total number of cans collected in two weeks. Let's assign a variable, c, to represent the number of cans collected in the second week. The inequality that represents the problem is: c + 145 > 380. To solve this inequality, we need to isolate the variable by subtracting 145 from both sides: c > 380 - 145. Simplifying further, we get c > 235. So, more than 235 cans of food were collected in the second week.

Answer:

-18

Step-by-step explanation:

The tall sticks around n+5 are absolute value signs. Basically, all you need to do is work out what the answer to the problem is inside the signs, then make whatever the answer is positive, then multiply by -9.

-7 + 5 = -2 (that turns into 2)

-9 x 2 = -18

Remark

One of the ways you could solve this is to go to a place like Desmos and graph it for yourself. Then at least you would know what the answer looked like. Another way is to solve for the x value by equating the equations since the y has to be the same. We'll do both.

Solve For X

(2/3)x + 1 = -(2/3)x - 1    Add 1 to both sides

(2/3)x + 1 + 1 = - 2/3x    Subtract (2/3x) from both sides.

2 = (-2/3)x - (2/3)x

Show the graph and comment

Notice that there is only one graph given that has a value of x = - 3/2 Normally you are not that lucky. Thanks for putting the graphs in. We are usually not that lucky and have to guess at the answer if it is a graph.

2 = - 4/3x                      Multiply both sides by 3

2 * 3 = - 4x    

6 = - 4x                          Divide by - 4

6/-4  = x                        Reduce

-3/2  = x

Remark

The x value is wrong for the one on the left.  It is also wrong for the third one from the left.  And the last graph is also incorrect.     Only the second from the left gives the right answer.
