JL = x+16

JK+KL = x+16

2x+16+7 = x+16

2x+23 = x+16

2x-x = 16-23

x = 7

A car is traveling at a steady speed. It travels 1 and one half

OLga [1]

Step-by-step explanation:

1.5 mi = 2 and 1/4 min

In 43 minutes:

43 ÷ 2.15 = 20 2.15 = 2 and 1/4 min

Now you have to multiply 1.5 by 20

1.5 x 20 = 30

In 1 hour (60 minutes):

60 ÷ 2.15 = 27.9

Now you have to multiply 1.5 by 27.9

1.5 x 27.9 = 41.85

Hope this was helpful :)

Elena and Jada are 25 miles apart when they start moving toward each other. Elena runs at a constant speed of 6 mph and Jada wal

Setler [38]

Answer:

The Time taken by Elena and Jade to meet up is 2.5 hours

Explanation:

Given,

Elena moves with a speed of 6mph while Jada walks at a speed of 4 mph

Also, Distance can be calculated by the formula

$Distance = Speed * Time$

To find out the Total speed, i.e., speed of both Elena and Jada as both of them are walking in opposite direction we should add the speed of both the persons, if in same direction we should subtract the values

Here it will be: $6 + 4$ = 10mph

Distance apart is given as 25 miles. Substituting the values,

$Distance = Speed * Time$

25 = $10 * time$

Time = 25/10

Time = 2.5 hour

Hence, It will take 2.5 hours to meet up.

Solve for x. x= Look at image

postnew [5]

Answer:

$x = 14$

Step-by-step explanation:

To find x, the following equation is generated given the available information:

$\frac{(x + 7) + x)}{x + 7} = \frac{12 + 8}{12}$

$\frac{2x + 7}{x + 7} = \frac{20}{12}$

$\frac{2x + 7}{x + 7} = \frac{5}{3}$

Cross multiply

$3(2x + 7) = 5(x + 7)$

$6x + 21 = 5x + 35$

Collect like terms

$6x - 5x = - 21 + 35$

$x = - 21 + 35$

$x = 14$

The table shows the amounts of food collected by two homerooms. Homeroom A collects 21 additional items of food. How many more i

Andreyy89

Let x be additional food item the homeroom B should collect to have greater item per student than homeroom A.

(22 +24 + x) / 16 > (30 + 42 + 21) /24

(22 +24 + x) > 3.875 (16)

X > 16

So they should collect more than 16 food item to have a greater item per student
