grade 7 math
Answer:
Step-by-step explanation:
7y+5z-2y+z
Group the two y and the two z together
7y-2y = 5y
5z+z= 6z

Explain how the percent equation relates proportional quantities
the percent equation being
PART = PERCENT * WHOLE
Answer: This is the best I could find for you
Step-by-step explanation:
"When the ratio of part to whole is equal to the ratio of a percent to 100, shows a percent equal to an equivalent ratio, we call it a percent proportion. A percentage is a fraction expressed with 100 as the denominator. When two ratios are equal, they are said to be in proportion."
When the ratio of part to whole is equivalent to the ratio of a percent to 100, shows a percent equal to an equivalent ratio, we call it a percent proportion. A percentage is a fraction expressed with 100 as the denominator. When two ratios are equal, they are said to be in proportion.

PLS HELP! ALSO INCLUDE AN EXPLAINATION LIKE I HAVE THE ANSWER I JUST DON'T KNOW HOW TO SOLVE IT.
-10 ≤ 2(2x + 7) ≤ 10.
Answer:
Step-by-step explanation: So first I changed 2(2x + 7) with the distributive property:
4x + 14
Since the above has to be less than or equal to 10, I know that x has to be negative.
If we make x = -1, 4x + 14 simplifies to -4 + 14, which simplifies to 10.
This satisfies the inequality, since it is greater than or equal to -10, and less than or equal to -10.
Hope this explained it well!
Answer:
-6 ≤ x ≤ -1.
Step-by-step explanation:
-10 ≤ 2(2x + 7) ≤ 10
Split it up into 2 inequalities:
2(2x + 7) ≥ -10 (reading from the middle to the left)
4x + 14 ≥ -10
4x ≥ -24
x ≥ -6.
and:
2(2x + 7) ≤ 10
4x + 14 ≤ 10
4x ≤ -4
x ≤ -1.
Combining the 2 we have:
-6 ≤ x ≤ -1.

Find the circumference and the area of a circle with radius 3 m
Use the value 3.14 for π, and do not round your answers. Be sure to include the correct units in your answers.
Answer:
The area: 28.26m^2, the circumference: 18.85m
Step-by-step explanation:
The area of a circle is 3.14(3)^2, which is 28.26, the circumference is 2(3.14)(3)=18.85m.
Answer:
Area of a circle= π[tex]r^{2}[/tex]
3.14 x [tex]3^{2}[/tex] = 18.84
The area of the circle is 18.84 [tex]m^{2}[/tex]
Circumference of a circle = 2πr
2 x 3.14 x 3 = 18.84
The circumference of the circle is 18.84 m
They are both the same number but the area is squared.
