Car A went 60km in 5/6hours while car B when 54km in 2/3hours which car was faster? How many times Faster?
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.

Combine like terms then solve for d. i will give brainliest please explain so i can know how to do it
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

The difference of complementary angles is 10⁰. Find the measures of the angle.
Answer:
40° and 50°
Step-by-step explanation:
Complementary angles sum to 90°
let x be one angle then x - 10 is the other, their sum is
x + x - 10 = 90
2x - 10 = 90 ( add 10 to both sides )
2x = 100 ( divide both sides by 2 )
x = 50
Then angles are 50° and 50° - 10° = 40°
Answer:
50° and 40°
Step-by-step explanation:
Since complementary angles are 90°, the angles combined have to equal to 90.
50 - 40 = 10
40 + 10 = 50
50 + 40 = 90

What is the solution to the system of equations?
2x – 3y = -1
y – x = -1
(a) Use the substitution method to find the solution.
(b) What do you know about the two lines in this system of equations (Hint: Do they intersect? Are they
parallel? Are they the same line?)
Siplified 1.6y

y=x + 5
A ( To check a system of equations by substitution, you plug your values for x and y into the original equations. If both simplified expressions are true then your answer is correct.
For example: To check if

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]

help find x pls geometry help plssss
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
