Question
Mashutka [201]

The equivalent value of given the expression is -17.25. Therefore, option C is the correct answer.

<h3>What is an equivalent expression?</h3>

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

The given expression is -14-8×0.5+0.75.

Now, -14-8×0.5+0.75

= -14-(8×0.5)+0.75

= -14-4+0.75

= -18+0.75

= -17.25

The equivalent value of given the expression is -17.25. Therefore, option C is the correct answer.

BRAINLIEST. NEED HELP NOW!!!<br> What is the value of x?
Arturiano [62]

Answer:

x=10

Step-by-step explanation:

these are similar triangles

8             12

------   = -----------

x+4          2x+1


using cross products

8* (2x+1) = 12(x+4)

distribute

16x + 8 = 12x+48

subtract 12x from each side

16x-12x +8 = 12x-12x+48

4x+8 = 48

subtract 8 from each side

4x+8-8 = 48-8

4x = 40

divide by 4

4x/4 = 40/x

x =10

PLEASEE HELP MEEE I DONT UNDERSTAND IT
Lorico [155]
<h2>Answer:</h2><h3>The answer should be, "The Least Frequency is at 13 Years."</h3><h3>-</h3><h3>The range should be 4, so that can't be it, and from the graph the frequency does not increase, it just goes down then back up.  Just based off the graph, it should be the 2nd choice :)</h3>
