Answer:

d. false, (3 × 6) + 4 < 8 + 4 + 32

Step-by-step explanation:

We want to determine whether, (3 × 6) + 4 = 8 + 4 + 32 is a true or false statement.

Let us first of all simplify the LHS of given expresion to get:

(3 × 6) + 4 = 18+4=22

The RHS is 8+4+32=12+32=44.

We can see that the LHS is less than RHS.

The correct answer is

d. false, (3 × 6) + 4 < 8 + 4 + 32

Describe two ways to solve the equation 2(4x-11)=10

shtirl [24]

2(4x-11) = 10

On dividing 2 on both sides

$\frac{2(4x-11)}{2} = \frac{10}{2}$

$4x-11 = 5$

On Adding 11 on both sides:

$4x-11+11 = 11+5$

$4x = 16$

On dividing both side by 4

$\frac{4x}{4} = \frac{16}{4}$

$x = 4$

Second way is:

We can use distributive property as

$2(4x-11) = 10$

$2*4x- 2*11 = 10$

$8x - 22 = 10$

On Adding 22 on both side

$8x - 22+22 = 10+22$

$8x = 32$

On dividing both side by 8

$\frac{8x}{8} = \frac{32}{8}$

$x = 4$

balandron [24]

Simple, just divide the number by the percentage and you get the original number. You can check it by multiplying the original number of 272 by 55% or .55 to get 150.
150/.55 = 272

It takes Carl 45 minutes to drive to work using two roads. She drives 32 mph on a small road for 1/2 hour. Then she drives 56 mp

Ksivusya [100]

Answer:

The Total distance she travel fro work is 30 miles .

Step-by-step explanation:

Given as :

the total time taken to cover distance = 45 minutes

Let The total distance cover = D miles

The distance cover at the speed of 32 mph = $D_1$ miles

The time taken to cover $D_1$ miles distance = $\frac{1}{2}$ hour

Distance = Speed × Time

∴ $D_1$ = 32 mph × $\frac{1}{2}$ h

or, $D_1$ = 16 miles

Again ,

The distance cover at the speed of 56 mph = $D_2$ miles

The time taken to cover $D_2$ miles distance = $\frac{1}{4}$ hour

∴ $D_2$ = 56 mph × $\frac{1}{4}$ h

or, $D_2$ = 14 miles

So , The total distance she travel for work = $D_1$ + $D_2$

Or, The total distance she travel for work = 16 miles + 14 miles = 30 miles

Hence The Total distance she travel fro work is 30 miles . Answer

Find all angle measures in the diagram

ycow [4]

Answer:

Step-by-step explanation:

Angles 3x+5, 75 and x all together make up 180 degrees (review "straight angles").

Thus, 3x + 5 + 75 + x = 180

Simplifying the left side, we get:

4x + 80 = 180, so that 4x = 100, and x = 25.

<KJL = 3(25) + 5 = 80 degrees

<NJM = 25 degrees

<MJL = 75 degrees
