Multiply using the FOIL method, then combine the real and imaginary parts of the expression.
what's an equivalent equation for -5(3-2x)
Answer:
-15 + 10x
or
10x - 15
(either one works)
Step-by-step explanation:
You mean you just want me to expand it?
Ok.
Multiply -5 by 3 and -2x.
(-5)(3) = -15
(-5)(-2x) = +10x
Add those together:
-15 + 10x
or
10x - 15

1. Use a ratio box to solve this problem. Tammy saved nickels and
pennies in a jar. The ratio of nickels to pennies was 2 to 5. If there were
70 nickels in the jar, how many coins were there in all?
Answer:
245
Step-by-step explanation:
let 'c' = total coins
2/7 = 70/c
2c = 490
c = 245

Step-by-step explanation:
A large square is divided into 4 smaller squares; then small left square is
divided into 4 smaller squares as well. What fraction of the large square is
shaded?
OPTIONS
4 over 5
3 over 8
4 over 9
1 over 3
1 over 2
Answer:
The total fraction shaded is 1/2
Step-by-step explanation:
Here, we want to know the fraction shaded
As we can see, the box is originally divided into 4
So each of the 4 parts are 1/4
for the first part, we have 4 divisions;
This means each of the divisions with respect to the whole fraction will be 1/4/4 = 1/16
Now, two of these are shaded, making 1/16 and 1/16
Secondly, we have half of the 1/4 : So with respect to the whole, we have 1/4/2 = 1/8
for the third part, the whole 1/4 is shaded
and lastly, we have an unshaded 1/4
so, the total fraction shaded will be ;
1/16 + 1/16 + 1/4 + 1/8
= (1 + 1 + 4 + 2)/16 = 8/16 = 1/2

On Monday, snow fell at a rate of 2.8 inches per hour.
Write an equation to show the relationship between the number of hours, h, and Monday's total snowfall, s.
Answer:
s = 2.8h
Step-by-step explanation:
Answer:
s = 2.8h
Step-by-step explanation:
2.8 inches of snow : 1 hour
Total snowfall = 2.8 × number of hours
2.8 × h = s
2.8h = s
Somebody please help me
Answer:
s²+r²=t² => r²=s²-t²= 27²-25²
The answer is D
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
'r' and 's' are legs and 't' is the hypotenuse
The Pythagorean Theorem takes the sum of the legs, squared, and sets them equal to the hypotenuse squared.
So in this problem we could start with:
r² + 25² = 27²
r² = 27² - 25²
to get 'r' by itself we take its square root, and what we do to one side of an equation we must also do to the other side, so:
r = [tex]\sqrt{27^2 - 25^2 }[/tex]
10 x 10 +100 – 1000 = X
Answer:-800
Step-by-step explanation: 10 times 10 is 100 plus another 100 is 200-1000 is -800 which is x
Answer:
-800
Step-by-step explanation:
since you need to mutiply first,
10 x 10 + 100 - 1000 = X
100 + 100 - 1000 = X
200 - 1000 = X
-800 = X

Which of the following are equal to 25 miles per gallon? Check all that apply
a car with an initial value of $23,00 is decreasing in value at a rate of 8% each year. Write a function, f(x), that expresses the value of the car in x years
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
A = P(1 - r/n)^ nt
Where
A represents the value after t years.
n represents the period for which the decrease in value is calculated
t represents the number of years.
P represents the value population.
r represents rate of decrease.
From the information given,
P = 23000
r = 8% = 8/100 = 0.08
n = 1
Therefore, the exponential decay function described in this situation is
A = 23000(1 - 0.08/n)1)^ 1 × t
A = 23000(0.92)^t
If A = 15000, then
15000 = 23000(0.92)^t
0.92^t = 15000/23000 = 0.6522
Taking log of both sides to base 10
Log 0.92^t = log 0.6522
tlog 0.92 = log 0.6522
- 0.036t = - 0.1856
t = - 0.1856/- 0.036
t = 5 years to the nearest year

really need help on these two questions for geometry, please actually answer it instead of just grabbing points and leaving :'), like most clowns on here
Answer:
Step-by-step explanation:
The diagonals of a rhombus are perpendicular, so ∠AED = 90° and ∠BEC = 90°.
∠DAE = 180° - ∠AED - ∠EDA = 180° - 90° - 35° = 55°
BD is a transversal across parallel sides AD and BC, so ∠EBC = ∠EDA = 35°.
∠BCE = 180° - ∠BEC - ∠EBC = 180° - 90° - 35° = 55°
