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

What is the distance between -25 and -12 on a number line? Pls help im literally so bad at math and i cant get another one wrong
Answer:
it would be 13
Just do 25 -12
Consider marking brainliest
Answer:
13
Step-by-step explanation:
1) use the formula of distance:
|-25-(-12)|
2) remember that - * - = +
|-25+12|
3) solve the operation
|-13|
4) remember that a distance can’t be negative

In circle A shown below, the measure of ∠BAD is 148°:
Circle A with angle BAD measuring 148 degrees; points B, C, D lie on Circle A.
If mArc BC is 102°, what is mArc CD? (3 points)
Group of answer choices
74°
46°
96°
148°
The angle of the arc CD is equal to 46°
Data;
arc m<BD = 148°arc m<BC = 102°arc m<CD = ?Length of an ArcIn most case, when presented with a problem involving an arc in a circle, we often use the formula of length of an arc. But in this case, the we can simply find the arc CD by just subtracting the arc BC from the bigger arc.
[tex]< CD = < BD - < BC\\ < CD = 148 - 102\\ < CD = 46^0[/tex]
The angle of the arc CD is equal to 46°

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

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
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.
