Answer:
1) 25
2)64
3)-10
4)53
5)36
6)60
7)33
Step-by-step explanation:
Substitute
1) 5(25)-100
125-100=25
2) 4*4*4=64
3)2(5)-20
=10-20
-10
4)7(4)+25
28+25
53
5) (3*3*3)+9
27+9
36
6) 4(20-5)
4(15)
60
7)6(4)+(3*3)
24+9
33
Step-by-step explanation:
For all of these problems, we are given the values of the variable x.
Now, we just need to input them into the equations.
1) 5x-100 x=25
5(25)-100
125-100= 25
2) x^3 x=4
4^3= 4×4×4= 64
3) 2x-20 x=5
2(5)-20
10-20= -10
4) 7x+25 x=4
7(4)+25
28+25= 53
5) x^3+9 x=3
3^3+9= (3×3×3)+9
27+9= 36
6) 4(x-5) x=20
4(20-5)
20(4)-5(4)
80-20= 60
7) 6x+y^2 x=4 and y=3
6(4)+3^2
24+(3×3)
24+9= 33
Hope this helps! :)
