Answer:

7d=30

d=18.5714

Step-by-step explanation:

Answer:

d=20

Step-by-step explanation:

4d & 3d are like terms because they both have a variable.

20 & 5 are alike because they both don't have a variable.

First you would add 4d and 3d together, and you will get 7d.

4d+20+3d-5=155

7d+20-5=155

Next you can subtract 5 from 20.

7d+15=155

Then you subtract 15 from both sides of the equation.

7d=140

Then you divide by 7 on both sides.

And you are left with d=20

Step-by-step explanation:

Answer:

Car B is 1.125 times faster than Car A.

Step-by-step explanation:

Speed = Distance / Time

Car A speed = Car A distance / Car A time

= 60 / (5/6) = 72km / hr

Car B speed = Car B distance / Car B time

= 54 / (2/3) = 81 km /hr

Car B is 81 / 72 ie = 1.125 times faster than Car A.

Answer:B

Step-by-step explanation:

Using proportions, it is found that:

A proportion is a fraction of a total amount.

In this problem, the markup is of 40% over an amount of $1000, hence:

0.4 x $1000 = $400.

Considering the markup, 100 bracelets will be sold for $1,400, hence, the price of each bracelet will be given by:

$1,400/100 = $14.

Answer:

x = 28

Step-by-step explanation:

From the figure attached,

In ΔABC and ΔADC,

AB ≅ AD [Given]

BC ≅ CD [Given]

AC ≅ AC [Reflexive property]

ΔABC ≅ ΔADC [SSS property of congruence]

Therefore, ∠ABC ≅ ∠ADC [CPCTC]

(4x + 13)° = (5x - 15)°

15 + 13 = 5x - 4x

x = 28

Answer:

x = -52

Step-by-step explanation:

-4x-46+46=-3x+6+46

-4x=-3x+52

-4x+3x=-3x+52+3x

Answer:

[tex] - 4(x + 10) - 6 = - 3(x - 2) \\ - 4x - 40 - 6 = - 3x + 6 \\ - x - 52 = 0 \\ x = - 52[/tex]

Answer:

x = -6

Step-by-step explanation:

3/2x + 8 = -1

3/2x = -9

x = -9 x 2/3

x = -6

Answer:

The triangle will not be possible.

this is because two side lengths can't expand 14 units.

in order for the triangle to work, the sum of the two short side lengths must be greater than the longer side.

however, 6+6 does not equal 14 it equals 12 this means that the triangle is not possible

Subtract the sums:

Answer and Step-by-step explanation:

Anything that is to the power of 0 is equal to 1. This is why 2 to the power of 0 is equal to 0.

0 is the only number such that for any number x, x + 0 = x. So, the reason that any number to the zero power is one is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.
