Answer:

Step-by-step explanation:

1.) Apply the distributive law

5x + 5 * 2

2.) Multiply the numbers

5 * 2 = 10 is equivalent to 5x + 10

3.) Group like terms

5x - 3 + 10

4.) Add/subtract the numbers

-3 + 10 = 7 is equivalent to 5x + 7

John paid $50 for renting a cycle for 5 hours. Which graph shows the relationship between the cost of renting a cycle for differ

SpyIntel [72]

Answer:

Graph A <==

Step-by-step explanation:

$ 50 for 5 hours......50/5 = 10...thats $ 10 per hr

so the equation would be : y = 10x...with x being the number of hrs and y being the total cost.

So ur x axis will be the hours and your y axis will be the total cost.

so ur answer is :the title of the graph is cycle renting. the x axis (the horizontal axis)...since it is the hours, will be labeled 0,1,2,3,4,5,6

the y axis (the vertical axis)...since it is the total cost, will be labeled

0,10,20,30,40,50,60. points are plotted on (1,10),(2,20), and (3,30)

Train a is traveling at 30 mph faster than train b. If train a travels 350 miles in the same amount of time that train b travels

GalinKa [24]

Answer:

20 mph

Step-by-step explanation:

Let speed of Train a = Va mph

Let speed of Train b = Vb mph

Va = Vb + 30

Let time taken for Train a = Ta

Let time taken for Train b = Tb

time taken = distance travelled/speed

Ta = 350/Va = 350/(Vb+30)

Tb = 140/Vb

But they both travel in the same amount of time.

So, Ta = Tb

$\frac{350}{v_{b} + 30}=\frac{140}{v_{b}}$

Cross multiply

$350v_{b} = 140(v_{b} + 30)\\\\350v_{b} = 140v_{b} + 4200\\\\350v_{b} -140v_{b} = 4200\\\\210v_{b} = 4200$

Divide both sides by 210

$\frac{210v_{b} }{210} \frac{4200}{210} \\\\v_{b} = 20 mph$

There are 6 rotten mangoes and 24 good mangoes in a bag. What fraction of the mangoes is rotten?

dem82 [27]

$\sf \bf {\boxed {\mathbb {Given:}}}$

Total number of rotten mangoes in the bag = 6

Total number of good mangoes in the bag = 24

$\sf \bf {\boxed {\mathbb {To\:find:}}}$

Fraction of the rotten mangoes to the total mangoes.

$\sf \bf {\boxed {\mathbb {Solution:}}}$

$\implies {\blue {\boxed {\boxed {\purple {\sf { \frac{1}{5} }}}}}}$

$\sf \bf {\boxed {\mathbb {Step-by-step\:explanation :}}}$

Total number of mangoes in the bag = Total number of rotten mangoes + Total number of good mangoes

➺ $\:6 + 24$

➺ $\:30$

Now,

Fraction = $\frac{Total \: \: number \: \: of \: \: rotten \: \: mangoes}{Total \: \: number \: \: of \: \: mangoes}$

➺ $\: \frac{6}{30}$

➺ $\: \frac{1}{5}$

Therefore, the fraction of the rotten mangoes to the total mangoes is $\sf\pink{\frac{1}{5}}$ .
