84/4=21
now take the 2 even numbers below 21 and the 2 even numbers above 21
18 +20 + 22 +24 = 84
the numbers are 18, 20, 22 & 24
2 - b.
3 - a.
I'm not sure about 4. Hope this helps!
Answer: 17.5
Step-by-step explanation:
7:10 = x:25
times both sides by 25
25(7/10) =x
than solve for x
X = 25 × (7/10)
X = 17.5
Solve for w by simplifying both sides of the equation, then isolating the variable.
w=−4
Let's solve your equation step-by-step.
22=2(w+7)−4w
Step 1: Simplify both sides of the equation.
22=2(w+7)−4w
22=(2)(w)+(2)(7)+−4w (Distribute)
22=2w+14+−4w
22=(2w+−4w)+(14) (Combine Like Terms)
22=−2w+14
22=−2w+14
Step 2: Flip the equation.
−2w+14=22
Step 3: Subtract 14 from both sides.
−2w+14−14=22−14
−2w=8
Step 4: Divide both sides by -2.
−2w
/−2
=
8
/−2
Answer:
w=−4
