Answer:
x = -2
y = 5
Step-by-step explanation:
2x - 3y = -19 ---------------------------(I)
7x+ 7y = 21 -----------------------------(II)
Multiply equation (I) by 7 and equation (II) by 3.Then add and so y will be eliminated and you will get the value of x
(I)*7 14x - 21y = - 133
(II)* 3 <u> 21x + 21y = 63 </u> {Now add}
35x = -70
x = -70/35
x = - 2
Plug in x = - 2 in equation (I)
2*(-2) - 3y = -19
-4 - 3y = -19
-3y = -19 + 4
-3y = -15
y = -15/-3
y = 5
Answer:
x = 24
Step-by-step explanation:
Given that:
(x+3)/3 = 9
multiplying both sides by 3
(x+3) = 9*3
(x+3)= 27
Subtracting 3 from both sides
x= 27-3
x=24

Answer:
B. SAS
Step-by-step explanation:
Ratio of sides equal:
4/2= 6/3
So the 2 sides are congruent and also share same angle between.
B. SAS is the similarity reason
Answer:
Step-by-step explanation:
Volume of the space that is not occupied = Volume of cube shaped box - volume of soccer ball

If the length is 3×width then length+width=4×width and the perimeter is 8×width=86, width=86/8=43/4=10.75cm.
The length is 3×10.75=32.25cm.
