Step-by-step explanation:
-25-2x=3x
I know the answer to the problem but i´m not sure how to move the constant (-25) to the other side. When you move the constant to the right side the equation should be -2x=3x+25. How do you move a constant to the other side?
In this case I believe you would add 25 to both sides. The -25 +25 would cancel out and then +25 would be on the right.
At the toy store, 4 toy cars cost $3.84. How much does it cost to buy 20 toy cars?
A. $20.20
B. $17.20
C. $19.20
D. $21.20
Whoever gets the correct answer will get a crown!!!
Step-by-step explanation:
To answer this, we need to find the scale factor which is to find how much one individual car is worth.
So we need to divide 3.84 and 4.
3.84 ÷ 4 = 0.96
So each car is $0.96.
To find 20 toy cars, we need to multiply 0.96 and 20.
The answer is:
$19.20

Answer: D
Step-by-step explanation:
Answer:
It would be answer c.
Step-by-step explanation:
When elevation is higher, there is less air pressure, which causes air molecules to spread out, and when its spreads out temperature decreases.
At a lower altitude, it is more humid because air molecules are more compact, which causes the temperature to be warmer, so the answer is c.

7th Grade math if anyone knows
Answer:
30° and 150°
Step-by-step explanation:
Supplementary angles sum to 180°
sum the parts of the ratio, 1 + 5 = 6 parts
Divide 180° by 6 to find the value of 1 part of the ratio
180° ÷ 6 = 30° ← value of 1 part of the ratio , then
5 parts = 5 × 30° = 150°
smaller angle = 30°
larger angle = 150°

Answer:
125:5

A set of middle school student heights are normally distributed with a mean of 150150150 centimeters and a standard deviation of 202020 centimeters. Darnell is a middle school student with a height of 161.4161.4161, point, 4 centimeters.
Complete question :
A set of middle school student heights are normally distributed with a mean of 150 centimeters and a standard deviation of 20 centimeters. Darnell is a middle school student with a height of 161.4 centimeters.
What proportion of student heights are lower than Darnell's height?
Answer:
0.716 (71.6%)
Step-by-step explanation:
Given that :
Mean, μ = 150
Standard deviation, σ = 20
Darnell's height, x = 161.4
(x < 161.4)
We obtain the standardized score, then find the proportion using a standard normal distribution ;
Zscore = (x - μ) / σ
Zscore = (161.4 - 150) / 20
Zscore = 11.4 / 20
Z = 0.57
P(Z < 0.57) = 0.71566 (Z probability calculator)
This means that about 0.716 (0.716 * 100% = 71.6%) of student's height are lower than 161.4 centimeters
Answer: 0.11
Step-by-step explanation:
Since we know the distribution of heights is normally distributed, the probability P(X>175) can be found by calculating the shaded area above X=175 in the corresponding normal distribution:
P(X>175)≈0.11 is the answer.

Solve for the value of x.
Answer:
x = 3
Step-by-step explanation:
x + x + x could also be written as 3x, and count the number of "1's" given on both sides:
3x + 4 = 13
=> subtract 4 on both sides of "="
3x = 9
=> Divide by 3 on both sides of "="
x = 3
Hope this helps!
Answer:
x=3
Step-by-step explanation:
I believe the answer would be x is equal to 3.
If you first create the equation you get 3x*4= 13
There are 3 green 'x' so that is 3x. The four orange boxes can be represented as 4, and the 13 orange boxes can be represented as 13.
Then, you solve the equation.
3x * 4 =13
Subtract 4 from both sides.
3x= 9
And simplify.
x=3.
I hope this helps! (:

Find the equation of the straight line with the
slope m= 1/2 and the y intercept is -1
Answer:
y = [tex]\frac{1}{2}[/tex] x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{1}{2}[/tex] and c = - 1 , then
y = [tex]\frac{1}{2}[/tex] x - 1 ← equation of line
