Answer:
135.1 cm
Step-by-step explanation:
The Pythagorean theorem tells you how to find the hypotenuse of a right triangle with legs 120 and 62:
diagonal = √(120² +62²) = √18244 ≈ 135.07
The length of one of the braces is about 135.1 cm.
Since y = 5x-1, we can fill it into 3x + 3y = -3. First, let's look at relating to a simpler equation. Let's say that x + y = 9 and y = 3 + 5. Now, we can fill it in to get that x + (3 + 5) = 9. Now, we know that 3+5 is 8, so x + 8 = 9. Now, x = 1. Likewise, we can do the same. For 3x + 3y = -3, all we need to do is to switch the y in 3x + 3y = -3 with 5x - 1. So it would become 3x + 3(5x - 1) = -3. Now we distribute to get 3x + 15x - 3 = -3. Now add three to both sides to get 3x + 15x = 0. Now simplify to get 18x = 0. Now we know that x = 0. Now fill x into y = 5x - 1. So y = 5(0) - 1. Now we know that y = -1.
To check fill in the answer to 3x + 3y = -3.
3(0) + 3(-1) = -3
0 + (-3) = -3
0 - 3 = -3
-3 = -3
Now that our check is completed we now know that x is 0 and y is -1.
Answer:
If its per month then its 900
Step-by-step explanation:
3600/4 = 900
900*4 = 3600
Answer:
d)c=4.20h
Step-by-step explanation:
the rate is 16.80 /4
4.20 per hour
earn = hours * rate
c = 4.20*h
Answer: 300.
Step-by-step explanation: 225/(No denominator) = 75/100.
225 doesn't go in 75. So, 75/100 divided by 5 = 15/20.
I want to find what number you multiply from 15/20 to get 225/(No
denominator). So, I divide 225 by 15. = 15, so multiply 15 x 15 = 225, and
the denominator, 20 x 15= 300.
