6x+3y=33..........(1)
4x+y=15
y=15-4x.........(2)
substitute value of y from (2) in (1)
6x+3(15-4x)=33
distribute 3 over the bracket
6x+45-12x =33
-6x=33-45
-6x=-12
x=2
plugging this value of x in equation 2 we get
15-4x=y
15-4(2)=y
y=15-8
y=7
Answer is x=2 and y=7
The answer must be A. For an explanation, please have a look at the picture.
Answer:
D
Step-by-step explanation:
3. 1*2* 1/3= 2/3 yd
4. 1/4 * 1/8 *2= 1/16in
6. 12 *4= 48ft
the numbers on the sides are the length, width and height. you multiply them all together to find the volume
