Square root of 30=5.5
square root of 35=5.9
square root of 40=6.3
square root of 45=6.7
square root of 50=7
Answer:
21
Step-by-step explanation:
35+? = 7(5+3)
35+? = 7(8)
35+? = 56
? = 56-35
? = 21
Divide 70 by -5
and flip the sign when dividing by a negative number
70/-5= -14
t(less than or equal to)-14
Answer:
q = -6
Step-by-step explanation:
8(q + 6)
= (8×q) (8×6)
= 8q + 48
8q = -48
q = -48/8
q = -6
1. By combining like terms
2. Same variable = same term, so you can combine them
3. Because 2y - y = 1y , and 1y is the same as y because a y is one y (obviously)
4. 1/2 + 1/2 = 1. A half an x and a half an x makes one whole x, therefore, x
5. No. You solve them like you would a normal equation with like terms. So it would be 3z^2
Hopefully these are right, I’m a bit rusty!
6. 4x
7. 3y
8. y - 4.5
9. 3.5x + 2
10. 4y + 2
11. 7x
12. 2.2w - 0.5
13. 23b + 6.6
14. 3.75x + 1.5
15. 0.8x + 2.1
Good luck, I hope this helped
