I need help with this last problem please
Answer:
25
Step-by-step explanation:
12+13=25 so 25x5=125 and 125 divide 5=25
I'm on computer so examples will look weird so I will label them.
Answer:
Your answer will be 25.
Step-by-step explanation:
1. You will rewrite the division as a fraction
Ex: 5 × (12+13)
____________
5
2. Cancel the common factor which is 5 so you will cross out the 5's
3. Then you would divide the (12+13) by 1
4. Finally you would add the 12 and the 13 to get 15.

Answer:
D. -31 is less than -23
Step-by-step explanation:
how to write a number increased by 11 is eaqual to twice the number decreased by 12
Answer: The number is 23
Step-by-step explanation:
Let x be the [number]
Rephrase the expression
a number increased by 11 is equal to twice the number decrease by 12
x+11=2x-12
Add 12 on both sides
x+11+12=2x-12+12
x+23=2x
Subtract x on both sides
x+23-x=2x-x
x=23
Hope this helps!! :)

Answer:
It’s B
Step-by-step explanation:
y'all I need help asap
Answer:
Let's solve for x.
4x+5y=7
Step 1: Add -5y to both sides.
4x+5y+−5y=7+−5y
4x=−5y+7
Step 2: Divide both sides by 4.
4x/4=−5y+7/4
x=−5/4 y+ 7/4
Answer: for the first one x=−5/4 y+ 7/4
3x−2y=−12
Step 1: Add 2y to both sides.
3x−2y+2y=−12+2y
3x=2y−12
Step 2: Divide both sides by 3.
3x/3=2y−12/3
x=2/3y−4
Answer:
x=2/3y−4

A person invests 9000 dollars in a bank. The
bank pays 6.5% interest compounded daily.
To the nearest tenth of a year, how long
must the person leave the money in the bank
until it reaches 31100 dollars?
Answer:
19 years approx
Step-by-step explanation:
Given dta
P= $9000
r= 6.5%
A= $31100
Calculate time, solve for t
t = ln(A/P) / r
substitute
t= ln(31100/9000)/0.06.5
t= ln(3.45)/0.06.5
t= 1.23/ 0.065
t= 18.92
Hence the time is 19 years approx

Step-by-step explanation:
to be a function, there has to be exactly one x for every y. if there is more than one per y, it makes it not a function. so, if there is two of the same number in the x, it's not a function.

Answer:
Step-by-step explanation: The first one would be -40 X 30. The parentheses around -25 turns it into a positive. And 5 make you round up
For 2, the -18 turns into a positive 18 bc of the parentheses. So round up to 20. Round 38 up to 40. 20 x 40
For 3, the negative 16 turns positive, making the equation -21 x 9 x 16. Round them to -20, 10, and 20. The equation is -20 x 10 x 20. Hope this helps!

If m<1 is 68° and m<3 is (3x - 7)º, what is x?
A. 25
B. 26 1/3
C. 49
D. 140
Answer:
C. 49.
Step-by-step explanation:
The measure of the angle below <1 = 68 degrees (vertical angles).
m < 3 = 72 + 68 External angle of a triangle theorem.
m < 3 = 140
3x - 7 = 140
3x = 147
x = 49.
Answer:
C
Step-by-step explanation:
The angle at the top of the triangle is vertical to ∠ 1 and congruent
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 3 is an exterior angle of the triangle, then
3x - 7 = 72 + 68 = 140 ( add 7 to both sides )
3x = 147 ( divide both sides by 3 )
x = 49 → C
