SOLVE RIGHT NOW PLEASE. Determine the solution to the system of equations below by using the ELIMINATION METHOD.

KiRa [710]

Answer: x=4 and y=3

Step-by-step explanation:

We start eliminating the same numbers with the same variable. So we take out 5y on both equation. We then subract 3x to 6x and we do the same to the right side. We end up having 3x=12 and then we divide 12/3=4. We plug 4 on the x values in one of the equation to find out the y value on that equation. You end up with y=3 and then plug that in the same equation on both to see if its right. Finally after that its correct.

The Budget Car Rental rates for renting a car for a day is shown in the table.

Irina18 [472]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

a.) Initial cost of renting the car is $100

b.) rate of change is slope, that is :

$\dfrac{105 - 100}{100 - 0}$

$\dfrac{5}{100}$

$\dfrac{1}{20}$

$0.05$

c.) Cost = C and distance = d

the equation will be :

$C = \dfrac{d}{20} + 100$

Can anyone explain please?

Answer:

x = 55

Step-by-step explanation:

In a rhombus, each diagonal bisects a pair of opposite angles.

For this parallelogram t be a rhombus, the angles with measures 2x - 40 and x + 15 must be congruent.

2x - 40 = x + 15

Subtract x from both sides.

x - 40 = 15

Add 40 to both sides.

x = 55

5 STARS!!!

Since it is given that Boris takes x minutes to run 5 miles it means that Boris' speed will be given as: $\frac{5}{x}$ .

Now, if Dylan runs slower than Boris and takes 12 more minutes to complete the 5 miles run, then that would mean that Dylan takes (x+12) minutes to complete the same run.

In this case we can see the Dylan's speed will be $\frac{5}{x+12}$ .

Thus, the denominator represents the time Dylan takes to run 5 miles if he takes 12 minutes more than Boris.

Therefore, out of the given options, the second option is the correct option.
