For every $9 invested in company A, $2 is invested in company B. Stacey quizzes her children, Krista and Kevin, about how much m

svet-max [94.6K]

Answer:

$108

Step-by-step explanation:

From the above question, we have the proportion:

Company A/Company B

= $9/$2 = x/x24

The next step is : We Cross Multiply

2x = $24 × $9

x = $24 × $9/2

x = $108

Therefore, she will invest in $108 company A if she invests $24 in company B.

What is the value for y?<br><br><br><br> Enter your answer in the box.

Anna007 [38]

Answer:

y = 28

Step-by-step explanation:

since this is an Isosceles triangle (x - 5)° must be equal to 34°

x - 5 = 34

x = 39

the sum of interior angles in a triangle is equal to 180°

if the two angles 34 + 34 = 68

Then the third angle is 180 - 68 = 112°

4y = 112

y = 28

-1.2= y/2.4 -1.7<br> Solve for y

evablogger [386]

${\huge{\boxed{\sf{Question}}$

$-1.2= y\div2.4 -1.7$

Solve for y

${\huge{\boxed{\sf{Answer\:with\:explanation }}}$

let's put our equation first

$-1.2= y\div2.4 -1.7$

Flip the equation

$y\div2.4-1.7=-1.2$

Now follow the rule of $BOMDAS/PEMDAS$

$y\div2.4-1.7=-1.2$

${\underline{simplify}}$

$0.416667y-1.7=-1.2$

add $1.7$ to both sides

$0.416667y=0.5$

Divide both sides by $0.416667$

$y=1.2$

${\huge{\boxed{\sf{Answer}}}$

$y$ would equal $1.2$
