Answer;
-2.5x-5
Step-by-step explanation:
first multiply whats in the () so -0.5 times 7z = -3.5z + -2 + 1z - -3
then combine like terms -3.5z + 1z = -2.5z
-2+-3= -5 so -2.5z - 5

subtract 13 from 30, and you get 17. Then you need to divide 17 and 30
Answer:x=−24/11
Step-by-step explanation:
Simplifies to:
x−86x=79
Let's solve your equation step-by-step.
x−86x=79
Step 1: Cross-multiply.
x−86x=79
(x−8)*(9)=7*6x
9x−72=42x
Step 2: Subtract 42x from both sides.
9x−72−42x=42x−42x
−33x−72=0
Step 3: Add 72 to both sides.
−33x−72+72=0+72
−33x=72
Step 4: Divide both sides by -33.
−33x−33=72−33
x=−2411
It is most likely going to be c. 11x7x1/10=77/11 which is the same as 11x7/10
Step 1: We make the assumption that 498 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=498$100%=498.
Step 4: In the same vein, $x\%=4$x%=4.
Step 5: This gives us a pair of simple equations:
$100\%=498(1)$100%=498(1).
$x\%=4(2)$x%=4(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{498}{4}$
100%
x%=
498
4
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{4}{498}$
x%
100%=
4
498
$\Rightarrow x=0.8\%$⇒x=0.8%
Therefore, $4$4 is $0.8\%$0.8% of $498$498.
