Answer:

\boxed{y - 8 + 2\leq  - 2 + 2}

Step-by-step explanation:

Which inequality is equivalent to this one:

y - 8 \leq  - 2

y - 8 + 8\geq  - 2 + 8

y - 8 + 8< - 2 + 8

y - 8 + 2 \leq  - 2 + 8

y - 8 + 2\leq  - 2 + 2

Let’s take the last inequality.

y - 8 + 2\leq  - 2 + 2

Subtract 2 on both sides.

y - 8 + 2-2\leq  - 2 + 2-2

y - 8 \leq  - 2

The inequality is equivalent.

Answer:

d. y minus 8 + 2 less-than-or-equal-to negative 2 + 2

Step-by-step explanation:

Which inequality is equivalent to this one?

<em>y minus 8 less-than-or-equal-to negative 2</em>

y minus 8 + 8 greater-than-or-equal-to negative 2 + 8

y minus 8 + 8 less-than negative 2 + 8

y minus 8 + 2 less-than-or-equal-to negative 2 + 8

y minus 8 + 2 less-than-or-equal-to negative 2 + 2

Take the last option:

y minus 8 + 2 less-than-or-equal-to negative 2 + 2

remove the +2 on each side to get

<em>y minus 8 less-than-or-equal-to negative 2</em>

2.4m log is cut into lengths into the ratio 7 : 5. Find the longer length in cm.
sergeinik [125]

Answer:

140 centimeters.

Step-by-step explanation:

Hello!

A 2.4 meter log is split into the ratio 7:5. Each unit part is one x-increment, so the log is split into 7 x-increments and 5 x-increments.

Find the longer length:

  • 2.4 into 7:5
  • 2.4 = 7x + 5x
  • 2.4 = 12x
  • x = 2.4/12
  • x = 0.2

Now, we must find the longer length, 7x.

  • 7x
  • 7(0.2)
  • 1.4

The longer length is 1.4 meters, but we want it in cm.

There are 100 centimeters in a meter.

  • 1.4 meters = 1.4 * 100
  • 1.4 meters = 140 centimeters

The longer length is 140 centimeters.

A salesperson earns $320 per week plus 8% of her weekly sales. The expression representing her earnings is 320 + 0.08x. Which of
Arturiano [62]

Answer:

Here, x represents the weekly sale

As per the statement:

A salesperson earns $320 per week plus 8% of her weekly sales.

"8% of her weekly sales" means \frac{8}{100}x = 0.08x

then;

the expression which represents her earning = 320+0.08x

"At least" means "\geq"

then;

the sales necessary for the salesperson to earn at least $1000 in the one week

⇒320+0.08x\geq 1000

Subtract 320 from both sides we have;

0.08x\geq 680

Divide both sides by 0.08 we get:

x\geq 8500

Therefore, the sales necessary for the salesperson to earn at least $1000 in the one week is: greater than or equal to $8500 i.e  x\geq 8500

Question 12 helllllllppppp plazzzzzzz
Eddi Din [679]

Answer:

Step-by-step explanation:

It says Renita takes minutes to ride half a mile.

She leaves 30 minutes before school.

Total distance is

               2\frac{1}{2} = \frac{1}{2}+ \frac{1}{2} +\frac{1}{2} +\frac{1}{2} +\frac{1}{2}\\

In

2\frac{1}{2} \ there \ are \ 5 \ times  \  \frac{1}{2} \ mile .\\

Therefore total time to reach school will be  5 x 5 = 25minutes.

Since she leaves 30minutes before school. She will reach 5minutes early before school.
