Answer:4z=-4
Step-by-step explanation:So you do distributive property 4×12 is 48 four times is 40 then you do 4Z +48 equals 44 then you subtract 48 from both sides because it’s edition so you change it to subtraction then once you subtract 48 from both sides 44 subtracted by 48 is -4 so for Z equals -4
Answer:
9 basket balls, 15 foot balls
Step-by-step explanation:
Let x be the number of basket ball
y be the number of foot ball
1 basket ball = $22
so x basket ball = 22x
1 foot ball = $30
so y foot ball = 30y
Total cost = 648
The equation becomes 22x+ 30y = 648
Given : They bought 6 more footballs than basketballs.
foot ball (y) = 6 more basket balls(x)
so y = x + 6
we solve for x and y
Now we plug in x+6 for y in the equation 22x+ 30y = 648
22x+ 30(x+6) = 648
22x + 30x + 180 = 648
Subtract 180 on both sides
52x = 468
Divide both sides by 52
so x= 9
Number of basket ball x= 9
Number of foot ball y=x+6= 9+ 6 = 15
22 white and 32 blue since 8 times 4 is 32 and 54 minus 32 is 22.
15 is the GcF for 45 and 60
0 is considered a solution because when you multiply both 4 and 2 by 0, you always get 0. when you add 10 to 0 you get zero, meaning that you get the same answer for both sides.
