Answer:
I found x for you, right there.
Answer:
Step-by-step explanation:
$15/2.5hr=$6 so if earnings are y and hours worked is x then
y=6x
A variable is a letter, for example x, y or z, that represents an unspecified number.
6 + x = 12
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.
18 cm^3
1/2 x 4 x 3 = 6
6 x 3 = 18
Answer:
1, (-5)(8)=-40 2, (4)(-4)=-16. 3, (-1)(-9)=9. 4 , (5)(6)=30. 5, (12)(-2)=-24. 6, (‐15)(9) =-135. 7. (5)(‐6)= -30. 8. 6(‐6) = -36. 9. (‐27)(14) = - 378. 10.(‐32)(0) = 0. 11.(128)(‐3)= -384. 12.(‐54)(‐4) = 216. 13.(+21) ÷ (+7)= +3
Step-by-step explanation:
positive number multiplied by positive number gives positive number
negative number (-ve) times positive number (+ve) gives -ve
-ve times -ve gives +ve
+ve times -ve gives -ve
hope it helps
