Answer:
This system has <em><u>infinite</u></em><em><u> number</u></em><em><u> of</u></em><em><u> solutions</u></em><em><u>.</u></em>
Step-by-step explanation:
It has 2 variables.
Answer:
9
Step-by-step explanation:
2(2z-4)=32
4z-4=32
4z=36
z=9
First find the mean (sum divided by number of values)
4+5+8+10+15=42
42/5=8.4
Then find the difference between each of the numbers and the mean.
4.4, 3.4, 0.4, 1.6, 6.6
Then find the mean of those values.
4.4+3.4+0.4+1.6+6.6=16.4
16.4/5=3.28
Final answer: 3.28
Answer:
see explanation
Step-by-step explanation:
The area (A) of the whole sign is calculated as
A =
bh ( b is the base and h the height )
Here b = 40 and h = 35, thus
A = 0.5 × 40 × 35 = 20 × 35 = 700 cm²
The area of the inner triangle is calculate as
A = 0.5 × 32 × 28 = 16 × 28 = 448 cm²
The area of the border is the difference between the whole sign and the inner triangle, that is
area of border = 700 - 44 8 = 252 cm²
Hoi!
To solve this, first plug in the values for x and y.

Turns into...

Now that we've got the values plugged in, let's solve.
4 × 2 = 8


× 3 =


is your answer. :)
