the sum of two numbers equals 49.The sum of the larger number and twice the smaller number is 70. what are the numbers.
Tell me the steps!
Answers
[tex]x = 49 - y[/tex]
Substitute that into,
[tex]49 - y + 2y = 70 \\ y = 21[/tex]
Substitute that into,
[tex]x = 49 - 21 \\ x = 28[/tex]
Answer check :
[tex]21 + 28 = 49 \\ 28 + 2(21) = 28 + 42 = 70[/tex]
Answer : The numbers are 21 and 28.
Hope this helps. - M
The problem is solved using a system of equations to find that the two numbers in question are 21 and 28.
To solve the problem involving two numbers where the sum equals 49 and the sum of the larger number and twice the smaller number equals 70, we need to form a system of linear equations and solve for the unknowns. Let's denote the smaller number as s and the larger number as l.
The sum of the two numbers is 49: s + l = 49.The sum of twice the smaller number and the larger number is 70: 2s + l = 70.Subtract the first equation from the second to find the value of s.
2s + l - (s + l) = 70 - 49
Which simplifies to:
s = 21
Substitute the value of s into the first equation:
21 + l = 49
And solve for l:
l = 28
Therefore, the smaller number is 21 and the larger number is 28.
A survey shows that 67% of peanut butter lovers prefer chunky-style. Out of 850 people surveys, how many can be predicted to say they prefer chunky-style peanut butter?

All you have to do is make you % into a decimal is multiply by 850
Hope this helps :-)
I like to use this formula cause it's really useful when it comes to these problems:
Part Percent
________ = _________
Whole 100
So, you basically plug in the numbers into the equation, it's really easy:
??? 67%
________ = ________
850 100
Then, you cross multiply. 67% x 850 = 56,950 / 100 =
And the answer to your question is: 569.6 or rounded is 570.

Note:
log_a c=b can be written as:
aᵇ=c
hence:
1. log₄ 16=2
will be written in exponential as:
4²=16
2. 25^(1/2)=5
will be written in logarithmic form as:
log₂₅5=1/2
3. Which function represents exponential growth?
#N/B For an exponential function:
y=a(b)^x
when b>1 it exponential growth
when b<1 it is an exponential decay
F: y=1/20(4)ˣ
b=4>1
exponential growth
G: y=16(0.4)ˣ
b=0.4<1
exponential decay
H: 20(1/8)ˣ
b=1/8<1
exponential decay
I. y=8x³
The above function does not have a growth factor, thus
it is a polynomial function not an exponential function.
4. Solve log₄3+log₄x=log₄18
when we add log functions we can multiply them as follows:
log₄(3*x)=log₄18
the log₄ will cancel and we shall remain with:
3x=18
solving for x we get:
(3x)/3=18/3
thus
x=6
5. Solve log₇36x-log₇2=log₇9
Dividing log functions is like subtracting them, thus we shall have:
log₇(36x/2)=log₇9
simplifying this we get:
log₇ 18x=log₇9
log₇ will cancel because of the same base and we shall have:
18x=9
thus
x=9/18
x=1/2
Expand the following:
Remember:
Multiplying logs is the same as adding them
Subtracting logs is the same as dividing them
thus
6. log₃ 4xy
expanding the above give us:
log₃4+log₃x+log₃y
Answer: log₃4+log₃x+log₃y
7. log₅ (xy²)/3
expanding this gives us:
log₅x+log₅y²-log₅3
Answer: log₅x+log₅y²-log₅3
Condense the following logarithms:
Using the concept from 6 and 7 we shall have:
8. log₈2+log₈7-log₈x
condensing this will give us:
log₈[(2*7)/x]
simplifying gives us:
log₈(14/x)
9. log₇9+3log₇y-4log₇2
Condensing the above gives us:
log₇9+3log₇y-4log₇2
=log₇9+log₇y³-4log₇2
=log₇(9*y³)/2
=log₇(9y³/2)

Kara and Steven are biking around a 1,800 kilometer path. They start biking from the same place, at the same time, and in the same direction. Kara bikes at a speed of 15 km/h and Steven bikes at a speed of 30 km/h. How long will it take before Steven and Kara will be at the same place of the path next time?
Answers
Time taken before the cyclist are on the same sport will be found as follows:
time=distance/(relative speed)
distance=1800 km
given that the cyclist will be riding towards the same side, then
relative speed=(Steve's speed-Kara's speed)=30-15=15 km/h
thus time taken will be:
time=1800/15
=120 hours

Solve the inequality and describe the solution set:
y-6 ≥ 12
Answers
You want to get the y only on one side of the equation. To get rid of the -6 you have to add 6 to both sides to even out the equation.
y-6≥12
+6 +6
y ≥18
Answer: The solution set is y≥18.
Step-by-step explanation:
Since we have given that
[tex]y-6\geq 12[/tex]
We need to first find the inequality and find the solution set.
[tex]y-6\geq 12\\\\y\geq 12+6\\\\y\geq 18[/tex]
So, the solution set for this would be all the values of y which is greater than 18.
i.e. y≥18.
