Answer:

m<1 = 84

m<2 = 6

Step-by-step explanation:

6x + x - 8 = 90

Combine like-terms

7x - 8 = 90

Isolate the variable

7x = 98

Divide each side by 7

x = 14

--------------------------------------

m<1:

6(x)

Substitute

6(14)

Multiply

m<2:

(x - 8)

Solve 4x^2 + 43 = 120. Round to the nearest hundredth.

Lady bird [3.3K]

4x² + 43 = 120
4x² = 120 - 43
4x² = 77
x² = 77/4
x² = 19.25
x = ±√19.25
x = ±4.39

The solutions are ±4.39</span>

The expressions a(8<img src="https://tex.z-dn.net/?f=x" id="TexFormula1" title="x" alt="x" align="absmiddle" class="latex-formul

amid [387]

Answer:

The expressions a(8x+7) and 4x + 3.5 are equivalent

Therefore, according to the above problem the equation is :---

$a(8x + 7) = (4x + 3.5) \\ 8ax + 7a = 4x + 3.5$

By comparing the term, we get

$8ax = 4x \\ 8a = 4 \\ a = \frac{4}{8} \\ \boxed{a = \frac{1}{2} }$

and,

$7a = 3.5 \\ a = \frac{3.5}{7} \\ \boxed{a = \frac{1}{2} }$

<h3>The value of "a" is <u>1/2</u>.</h3>
