Answer:
Step-by-step explanation:
Isolate any variable, x or y, but since y has already been isolated, use y to solve for x.
Substitute y into the first equation -3x-3y=3
This equals -3x - 3 (-5x - 17) = 3
Distribute to get -3x + 15x + 51 = 3
Then bring like terms together. -3x + 15x = 3 - 51
12x = -48
Solve for x
x = -4
Substitute -4 for x in the equation: y = -5x - 17
y = − 5x − 17
y = (−5) (−4) − 17
y = 20 - 17
y = 3 ( Simplify both sides of the equation)
Answer:
x = − 4 and y = 3
Answer:
: 1
Step-by-step explanation:
they are both divisible by 4 so you divide. You will get 4:3. Since you wanted n:1 , you have to divide both sides by 3. the answer is : 1

Answer: the correct answer is 60-3h<32
Step-by-step explanation:
<span>Part A:
</span>Surface area = 3.14(2*3 + 2²<span>)
</span><span>Part B:
</span>Surface area = 3.14(2*3 + 2²)
= 3.14(6 + 4)
= 3.14 * 10
= 31.4 units²
