Answer:
-45x - 18
Step-by-step explanation:
distributive property
Answer:
x = 18/45 (or, in a decimal, 0.4). Someone correct me if I'm wrong. :)
Step-by-step explanation:
We have to use the distributive property here. That means that you multiply -5x by 9 and -2 by 9. So...
9*-5x = -45x
9*-2 = -18
-45x = -18
Now, divide both sides by 45...
-45x/45 = -18/45
x = 18/45 should be the answer.

The Problem: Phillips Health and Beauty Spa is replacing one of its workstations. The interest on a loan secured by the spa was $93.50. The money was borrowed at 5.5% simple interest for 2 years. What was the amount that they borrowed?
Answer:
$850
Step-by-step explanation:
Amount that was borrowed = interest / (interest rate x time)
93.50 / (0.055 x 2) =
93.50 / 0.11 = $850

8. In AABC, mC = 90° and sin A =
What is m angle B in degrees?
A. 30°
B. 45°
C. 60°
D. There is not enough information to determine.
Answer:
C
Step-by-step explanation:
The degrees of a triangle add up to 180.
Angle C is already 90 degrees therefore angle A + angle B = 90 degrees.
Angle A is equal to sinA=1/2.
sinA=1/2 is equal to 30 degrees if you press 2nd, sin (1/2) into the calculator. You may also know this if you have memorized the values of trig.
90-30=60.
That leaves you with 60 degrees for angle B.

Ariana wants to ride her bicycle 37 miles this week. She has already ridden 14 miles. If she rides for 5 more days, write and solve an equation which can be used to determine xx, the average number of miles she would have to ride each day to meet her goal.
Answer:
4.6 miles for 5 days.
Step-by-step explanation:
37 - 14 = 23
23 divided by 5 = 4.6
Dilate Point B by a scale factor of 1/2
Answer:
( -1.5 , 1 )
Step-by-step explanation:
Hello There!
When dilating a point we divide or multiply the coordinates by whatever the scale factor is
Because the scale factor is 1/2 we just have to divide the coordinates of point B by 2
Preimage coordinates - ( -3 , 2 )
-3/2=-1.5 or -3/5
2/2=1
Dilated image coordinates ( -1.5 , 1 )
1) James deposited $4,000 into an account. He made
no additional deposits or withdrawals. James earned
5.75% annual simple interest on the money in the
account.
What was the balance in dollars and cents in James
account at the end of 5 years?
Answer:
$5150
Step-by-step explanation:
Given data
Principal=$4000
Rate=5.75%
Time= 5 years
The expression for the balance on simple interest is
A=P(1+rt)
substitute
A=4000(1+0.0575*5)
A=4000(1+0.2875)
A=4000X(1.2875)
A=$5150
Hence the balance is $5150

Find the indicated side of the
triangle.
b = 7 [?]
b is a diagonal of a square. Diagonal is just [tex]a\sqrt{2}[/tex] which means that b is equal to [tex]7\sqrt{2}[/tex].
Which inequality best represents the range of the part of the quadratic function graphed on the grid?
Answer:
It's B
Step-by-step explanation:
The line is on the x so it will be something with x in the answer. -9 or 0 or not present so it is B

Can someone help me asap
Answer:
1) 4
2) 5
3) -23
4) 8
5) 7
6) -64
7) -10
8) 19
9) 9
10) -56
Answer:
1) = -4
2) = 5
3) = 17
4) = 8
5) = 7
6) = -64
7) = -10
8) = 19
9) = 9
10) = -56
Step-by-step explanation:
1) (-4 + 2)^2 = -2^2 = -4
2) 25 / (9 - 4) = 25 / 5 = 5
3) 4 * 5 - 3 = 20 - 3 = 17
4) 2(2 + 2) = 2 * 4 = 8
5) (-10 + 5) / 5 + 8 = -5 / 5 + 8 = -1 + 8 = 7
6) (-3 - 1)^3 = -4^3 = -64
7) 5(5 - 7) = 5 * -2 = -10
8) 2 * 7 + 5 = 14 + 5 = 19
9) (5 * 3 + 3) / 2 = (15 + 3) / 2 = 18 / 2 = 9
10) 8(-1 - 6) = 8 * -7 = -56
Ruth wants to put a birdseed mix in her birdfeeder. The mix is 30% wild bird seed and 70% sunflower seed. Her birdfeeder can hold 8 cups of birdseed. How many cups of the mix will be wild bird seed?
Answer:
2.4 of the cups
Step-by-step explanation:
30% of 8 = 2.4
70% of 8 = 5.6
30% + 70% = 100%
2.4 + 5.6 = 8
A train travels 5 miles in 12 minutes at this rate how far will go in two hours
Answer:
Well, 60 (minutes in an hour) divided by 12 (from the problem) is 5, so you have to multiply that 5 by the 5 from the problem to find that the train is going 25 (5*5) mph. Just double this for two hours, and you result in 50!
Step-by-step explanation:

{45x+6y=15-x+18y=11 is..........................
Answer:
Step-by-step explanation:
45x+6y=15
-x+18y = 11
let's use elimination, the other way is by substitution, either way works but, it looks to me like elimination would be easy with the 'y'
3(45x+6y=15)
135x + 18y = 45 ( subtract 2nd eq. from 1st )
-( -x+18y = 11 )
136x +0y =34
x = 34 /136
x = 1 /4
there is X
plug that back into either of the 1st or 2nd equations to solve for y
- 1/4 + 18 y = 11
18y = 11 1/4
18y = 45/4
y = 45/4 * 1/18
y = 45/ 72
the fractions seem "difficult" but that's just what the given problem finds
