Answer:
x < - 2
Step-by-step explanation:
7 < 3 - 2x ( add 2x to both sides )
2x + 7 < 3 ( subtract 7 from both sides )
2x < - 4 ( divide both sides by 2 )
x < - 2

What is 8 1/3 - 3 1/2?
Answer:
4 5/6
Step-by-step explanation:
Turn both 8 1/3 and 3 1/2 into improper fractions (just to make it less complicated).
8 1/3 = 25/3
3 1/2 = 7/2
Then, try and make the denominators the same by finding the LCD (least common denominator).
The least common denominator of 3 and 2 is 6. Multiply both the denominators (3 and 2) to get 6, multiply the numerator with it as well (I can't explain this part properly, but the fractions will somehow explain).
[tex]\frac{25*2}{3*2}[/tex] = [tex]\frac{50}{6}[/tex]
[tex]\frac{7*3}{2*3}[/tex] = [tex]\frac{21}{6}[/tex]
So, then subtract (50/6 - 21/6).
50/6 - 21/6
= 29/6 = 4 5/6
So, 8 1/3 - 3 1/2 is 4 5/6.

Yvette paid $921 for tires for her car. She got special financing with a 0% interest rate if she paid off the tires in 6 months. How much will she have to pay each month in order to pay off the tires before she will have to pay interest?
a
$183.50
b
$153.50
c
$76.75
d
$92.10
Answer: B
Step-by-step explanation:
In 6 months she will have to pay $921
In 1 month she has to pay [tex]\frac{921}{6}[/tex] = $153.50
Each month, Yvette has to pay $153.50 in order to pay off the tires before she will have to pay interest
Therefore, B is the correct answer
Which is a factor of both terms of the expression 6f−12?
Answer:
6(f-2)
Step-by-step explanation:
Answer:
Step-by-step explanation:
If you solve the highest common factor first, then you can look for other factors.
Solution
6 = 2 * 3
12 = 2*2*3
The highest common factor is one 2 and one 3 making 6.
Use the distributive property to show what the 2 factors look like when the common factor is taken out.
6( f - 2)
Other factors.
You could take out just 1 factor like 2 or 3
2(3f - 6)
3(2f - 4)
Answer
I would submit 6(f - 2)

X - y = -2 7x + 2y = -5
Élimination method
Answer:
x = -1, y = 1
Step-by-step explanation:
Multiply the top equation by 2:
[tex]2x - 2y = - 4[/tex]
Leaving the bottom equation unchanged, add the two resulting equations to eliminate y, obtaining:
[tex]9x = - 9[/tex]
Solve this for x, and then substitute this value of x into the bottom equation. Finally, solve for y.
[tex]x = - 1[/tex]
[tex]7( - 1) + 2y = - 5[/tex]
[tex] - 7 + 2y = - 5[/tex]
[tex]2y = 2[/tex]
[tex]y = 1[/tex]

Answer:
[tex]\sf \dfrac{4}{5}[/tex]
Step-by-step explanation:
(3,7) ⇒ x₁ = 3 & y₁ = 7
(8 ,11) ⇒ x₂ = 8 & y₂= 11
Slope
[tex]\boxed{Slope = \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}}[/tex]
[tex]\sf =\dfrac{11 -7}{8 -3}\\\\\\ = \dfrac{4}{5}[/tex]
A right rectangular prisim has a length of 2 1/2 feet a width of 3 feet and a height of 1 1/2 feet. Unit cubes with side lengths of 1/2 foot are added to completely fill the prisim with no space remaining. What is the volume in cubic feet of the right rectangular prisim?
A frog starts jumping from the middle of a circular pond.
The pond is 12 metres across, from one side to the other.
43
The frog always jumps half the distance left to the edge of the pond.
How far is the frog from the edge after 3 jumps?
Answer:
Step-by-step explanation:
Remark
You could do this simply by taking 3 jumps, without using a formula. That would work as well, but I think it is easier just to make 3 jumps.
Jump One
The frog starts out 6 meters from an edge. (He/she starts at the middle). The frog makes 1 jump.
He lands 3 meters (1/2 the distance) from the edge.
Jump Two
He jumps in such a way that he is 1/2 the distance from the edge. So far he is 3 meters away. His jump puts him 1 1/2 meters from the edge.
Jump Three
The frog makes one last jump. It is 1 1/2 meters from the edge. The third jump takes it 1/2 * 3/2 = 3/4 a meter away from the edge.
Answer: 3/4 of a meter from the edge.

Which of the following are identities? Check all that apply.
A. sin(x+y)+ sin(x - y) = 2cos x siny
B. cos(x + y) + cos(x- y) = 2cos x cosy
C. tan(x - 2) = tan x
D. COS(x + y) - cos(x - y) = 2 cos xcosy
Answer:
B. cos(x+y) + cos(x-y)= 2cosx.cosy
Step-by-step explanation:
cos(x+y) + cos(x-y)
= cosx.cosy - sinx.siny + cosx.cosy + sinx.siny
=cosx.cosy + cosx.cosy
=2cosx.cosy
find the measures of m and n
Answer:
m=3 n=6
Step-by-step explanation:
top diagonals are congruent
9 = 3m
solve for m
m = 3
bottom diagonals are congruent
m + 8 = 2n -1
plug in 3 for m
3 + 8 = 2n -1
solve for n
11 +1 = 2n
12 = 2n
n=6

Find the surface area. HELP PLEASE!!!!
Answer:
I think the answer is 792
Answer:
SA = 696cm^2
Step-by-step explanation:
First we need to identify the shapes
There are 3 rectangles and 2 triangles
Now the individual surface area for each shape
20 x 10 = 200 (1 rectangle)
1/2(12 x 8) = 48 (1 triangle)
Now we add them together
(200 x 3) + (48 x 2) = 696
