Answer:
x=2
Step-by-step explanation:
4x=-x+10
To find x, we first add x to each side to get rid of -x on the right side.
5x=10
Then, we divide each side by 5 to get x by itself.
x=2
And that's your answer :)

Simplify the expression by combining like terms
Expression:-12x - 4x - 72 +10y3
Like Terms:
I
Simplified Expression:
> |
Answer:
Step-by-step explanation:
So you are combining the numbers that look alike practically..
They are asking for how many like term, so you would put how many numbers you see that are different.
-12x - 4x - 72 + 10y^3
-16x - 72 + 10y^3
That is as far as you could go.
There are 3 numbers that look different.
When I say this I mean that one number has no variable, one number has a variable, and another number has a variable and it’s cubed.
So that would be 3 like terms.
And for the simplified form, it’s
-16x - 72 + 10y^3

A circle is subdivided by a central angle of 90 degrees. The length of the subtended arc is 25 mm. What is the radius of the circle?
A:
[tex] \frac{50}{\pi} mm[/tex]
B:
[tex] \frac{\pi}{50} mm[/tex]
C:
[tex] \frac{25\pi}{2} mm[/tex]
D:
[tex]25mm[/tex]
Answer:
[tex](\text{A})\:\frac{50}{\pi}\:\text{mm}[/tex]
Step-by-step explanation:
This the arc is 90 degrees and there are 360 degrees in a circle, it makes up [tex]\frac{90}{360}=\frac{1}{4}[/tex] of the circle. Therefore, its length will be [tex]\frac{1}{4}[/tex] of the circumference. Since its length is 25 mm, the circumference is then [tex]25\cdot 4=100\:\text{mm}[/tex]. The circumference of a circle is given by [tex]2\pi r[/tex], where [tex]r[/tex] is the radius of the circle. Therefore, we can set up the following equation and solve for [tex]r[/tex]:
[tex]2\pi r=100[/tex]
Solving, we get:
[tex]2\pi r=100,\\\\r=\frac{100}{2\pi},\\\\r=\boxed{(\text{A})\:\frac{50}{\pi}\:\text{mm}}[/tex].

Find the gcf of 20,50
Answer:
10
Step-by-step explanation:
Answer:
The GCF is 10
Step-by-step explanation:
The following factors that fit into 20 and 50 are as follows
1
2
5
10
We can go higher than 10, BUT, we would have to multiply that number by a decimal.
Therefore, 10 is greatest common factor

a line has a slope of -3, so it's equation has the form y= -3x + b. the line passes through the point (1, -2). what is the y-intercept, b, of the line?
Answer:
y-intercept = 1
Step-by-step explanation:
y = -3x + b
(1 , -2)
Plugin the equation
-2 = -3*1 + b
-2 = -3 + b
-2 + 3 = b
1 = b

Answer:
90deg
Step-by-step explanation:
If the angles are supplementary, that means mA + mB = 180*
we know that
mA = (2x + 8)deg
mB = (2x + 8)deg = mA
mA + mB = 180deg
mB + mB = 2mB = 180deg
mB = 90deg
Note, that we did not need to compute x even, because the angles were the same.
If you subtract 27 from the product of a number and 8, you get 1789.
Translate the statement to equation

Answer:
8x-27=1789
Step-by-step explanation:
Which of the four statements is true and also write a one-step inequality as an example of when you would "flip" the sign.
Step-by-step explanation:
There are 5 types of Inequality sign :
1. = read '' equals to ''
2. > read '' greater than ''
3. < read '' less than ''
4. ≥ read '' greater than or equals to ''
5. ≤ read '' less than or equals to ''
Example -
1. 2 = 3 ( 2 is equals to 3 )
2. 3 > 2 ( 3 is greater than 2 )
3. 2< 4 ( 2 is less than 4 )
4. 3 ≥ 2 ( 3 is greater than or equals to 2)
5. 2 ≤ 4 ( 2 is less than or equals to 4 )
One - step inequality :
Addition and Subtraction Properties of Inequality -
If a > b, then a + c > b + c
If a > b, then a − c > b − c
Multiplication and Division Properties of Inequality -
If a > b, then ac > bc, if c > 0
If a > b, then ac < bc, if c < 0
If a > b, then [tex]\frac{a}{c} > \frac{b}{c}[/tex], if c > 0
If a > b, then [tex]\frac{a}{c} < \frac{b}{c}[/tex],, if c < 0
The inequality x > y can also be written as y < x. The sides of any inequality can be switched as long as the inequality symbol between them is also reversed(or flip ).Solving inequalities is same as solving equations, except you have to reverse( or flip ) the inequality symbols when you multiply or divide both sides of an inequality by a negative number.Brian invests £1850 into his bank account. He receives 2.7% per year simple interest. How much will Brian have after 3 years? Give your answer to the nearest penny where appropriate.
Answer:
£1999.85
Step-by-step explanation:
A = P(1 + rt)
Where:
A = Amount after t years
P = Initial amount invested = £1850
r = Interest rate = 2.7%
t = Time in years = 3 years
Calculation:
First, converting R percent to r a decimal
r = R/100 = 2.7%/100 = 0.027 per year.
Solving our equation:
A = £1850(1 + (0.027 × 3))
A = £1999.85
Therefore, Brian will have £1999.85 after 3 years.
