Answer:

${ \tt{ - \frac{h}{3} - 17 = 25 }} \\$

• Apply additional property of equality:

$→ \: { \tt{ - \frac{h}{ 3} = 25 + 17 }} \\ \\ → \: { \tt{ - \frac{h}{3} = 42}}$

• Apply cross multiplication, multiply either sides by -3:

$→ \: { \tt{( - \frac{h}{3} \times - 3) = 42 \times - 3 }} \\ \\ → \: { \tt{h = - 3 \times 42}} \\ \\ → \: { \underline{ \tt{ \: \: h = - 126 \: }}}$

Answer:

Last week the owner spend $42.32 on waffle cones.

Step-by-step explanation:

Given:

An ice cream shop owner pays $0.12 per regular cone and $0.23 per waffle cone. Customers are allowed to choose which type of ice cream cone they would prefer.

If two thirds of the 276 vibes sold last week were waffle cone.

Now, to find the amount the owner spend on waffle cones last week.

Last week waffle cone sold were = $\frac{2}{3}\ of\ 276.$

$=\frac{2}{3} \times 276\\\\=\frac{552}{3} \\\\=184.$

Last week number of waffle cones sold were = 184.

Price of per waffle cone = $0.23.

Now, to get the owner spend on waffle cones last week we multiply last week number of waffle cones sold were by price of per waffle cone:

$184\times 0.23\\\\=\$42.32.$

Therefore, last week the owner spend $42.32 on waffle cones.

The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less

svp [43]

Answer:

Raul's age is 15 years.

Step-by-step explanation:

r represents Raul's age.

The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less than three times Raul's age.

The first presidential election happened 39 years after the Great Depression and six years less than three times Raul's age is 3r - 6.

Therefore, 3r - 6 = 39

Add 6 to both sides.

3r = 45

Divide both sides by 3.

r = 15

Hence, Raul's age is 15 years.
