Answer 2
Answer:
X= 1
Step-by-step explanation:
5x^2 +5x-4=2x-3. 25x+5x=30x
25x+5x-4=2x-3.
30x-4=2x-3. 30x-2= 28x
28x-4=-3
add +4 to both sides
28x/28 = 1/28
x=1

a 200 kg car is being pushed along a road with a force of 3000 Newtons and is receiving a frictional force of 300 Newtons. calculate the acceleration of the car
please help people keep ruining the awnser HELP
Answers
Answer:
Friends, the sum of forces is 3000-300 =2700, and then according to Newton's law F=ma, m=200kg, through deformation can get a=F/m, that is, a=2700/200=13.5m/s², maybe I was wrong, you can try it yourself
Step-by-step explanation:
F：3000N-300N=2700N
F=ma=>a=F/m
a=2700N /200kg
=13.5m/s².

if 3x/4 - 13 = -9 then what is the value of x^2
show work!
Answers
Answer:
When 3x/4 - 13 = -9, x² = 256/9.
Step-by-step explanation:
3x/4 - 13 = -9
Multiply the expression by 4.
3x - 52 = -36
Add 52 to both sides.
3x = 16
Divide both sides by 3.
x = 16/3
Knowing x, let's square it.
(16/3)²
Apply the power to fraction rule.
16²/3²
Evaluate the powers.

(5x + 2) = 102º
(3x + 5) = 65º
(8x + 8) = 168º
(4x + 15) = 95º
(5x + 10) = 110º
Step-by-step explanation:
(5x + 2) + (3x + 5) + (8x + 8) + (4x + 15) + (5x + 10) = 540
Group like terms
(5x + 3x + 8x + 4x + 5x) + (2 + 5 + 8 + 15 + 10) = 540
Simplify
25x + 40 = 540
Subtract 40 from both sides
25x = 500
Divide both sides by 25
x = 20
--------------------
Now that x has been determined the angles can be found
(5x + 2) = 5*20 + 2 = 102º
(3x + 5) = 3*20 + 5 = 65º
(8x + 8) = 8*20 + 8 = 168º
(4x + 15) = 20*4 + 15 = 95º
(5x + 10) = 5*20 + 10 = 110º
What is 2+2.2*46-13(41+3 x)-16x
Answers
Answer:
7912.8x
Step-by-step explanation:
First do what in the parenthesis (41+3x)=44x
Then what to the left of the ()
2+2.2*46-13=180.2
then multiply what you got in the () to what we just got
180.2*44x=7928.8x
finally we subtract it to the -16x
7928.8x-16x=7912.8x

highest common factor of 16 and 50
Answers
Answer:
2
Explanation:
GCF of 16 and 50 is 2. The highest common factor is also known as the great common factor.
The highest common factor of the numbers 16 and 50 is 2.
What is the highest common factor?
The greatest positive integer that divides two or more integers without producing a remainder is known as the highest common factor (HCF). Also, it is known as the largest common divisor (GCD).
To find the highest common factor (HCF) of 16 and 50, we can use a method called prime factorization.
First, we can find the prime factorization of each number:
16 = 2 × 2 × 2 × 2
50 = 2 × 5 × 5
Next, we can identify the common factors between the two prime factorizations. The only common factor is the factor of 2, which appears in both prime factorizations.
Therefore, the highest common factor of 16 and 50 is 2.
