Answer:
for the 1st one the answer is x= 3 y=1 and the second one is x= 5 and y = 3 and 1/3
Step-by-step explanation: so basically for the first one -5 times x which is 3 is -15 right? and then 5 times y which is 1 is 5 right so -15 plus 5 = -10
second one is x = 5 and y = 3 and 1/3 because 5*x which is 5 is = to 15 right? and then 3 times y which is equal to 3 and 1/3 is equal to 10 which when you do 15-10 in pretty sure it equals 5 correct me if im wrong
Hope this helps xD ;)
Answer:
512
Step-by-step explanation:
when q = 2, w = 3
4q(q + 3w)^2
= 4(2) ((2)+3(3))^2
= 512
In the picture are the answers
The answer is 8 because when you replace x by 8 it equals 24
Let height of house be x.
Oak tree = 120 + x
Also given,
Oak tree = 2.5x
120 + x = 2.5x
1.5x = 120
0.3x = 24
3x = 240
x = 80
Hence, the height of the house is 80 ft.
