7y+5z-2y+z
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
(a variable with out a number is = to 1)
so it would be 5y+6z
Hope this helps
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.

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.

proportional or not proportional?
Answer:
Proportional
Step-by-step explanation:
The relationship is proportional because starting at (0,0) there's a constant rate between the number of plants and the number of roses. We can represent this proportional relationship as y=5x where k=5, the constant of proportionality.
How would I find the range btw im only allowed a Ti-84 calculator So pls tell me how to solve this without using any stepbystep caulculators or desmos
Answer:
D
Step-by-step explanation:
u dont really need a calculator for this problem
to find the answer, you have to look at the equation.
f(x)=20x+4
the 4 is the y-intercept (0,4), which tells us that the range will start from number 4.
the 20x tells u to multiply the x by the 20
so if it was 20(1)=20, 20(2)= 40, 20(3)= 60 ....
so if you add x amount of plates to the barbell, it will be 20 times x plus 4(because 4lbs is the weight of the barbell itself)
so 0 plates is 4, 1 plate is 20(2) + 4 = 44, 20(4)+4= 84 ....
(i didnt do 20(1) or 20(3) because you need to have a even number of plates of each side of the barbell.)
