Answer:
Step-by-step explanation:
An army base had provisions for 300 soldiers for 90 days. After 20 days, there should be provisions enough for 300 soldiers for another 70 days
= 21000 soldier-day
50 soldiers left so there are 300-50 = 250 soldiers left
if they consume food at the same rate, the remaining provisions will last
= 21000/250
= 84 days

Find the value of the following expression.
Answer: 25 I believe
Answer:
25
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)^c = a^(bc)
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c)
a^0 = 1 . . . for a≠0

Sam will take four science tests this quarter. Her scores on three of the tests
are shown below.
Test 1
83%
Test 2
91%
Test 3
88%
Test 4
?
What does Sam need to score on the fourth test to ensure that she will have an
average of 90% for all four tests?
%
Answer:
98%.
Step-by-step explanation:
The following data were obtained from the question:
Test 1 (T₁) = 83%
Test 2 (T₂) = 91%
Test 3 (T₃) = 88%
Test 4 (T₄) =?
AVERAGE = 90%
We can obtain the score of 4th test by doing the following:
AVERAGE = (T₁ + T₂ + T₃ + T₄) /4
90 = (83 + 91 + 88 + T₄) /4
90 = (262 + T₄) /4
Cross multiply
90 × 4 = 262 + T₄
360 = 262 + T₄
Collect like terms
360 – 262 = T₄
T₄ = 98%
Therefore, Sam need to score 98% in the 4th test in order to have an average score of 90%.

Answer:
y = x - 6y = -x + 5y = x - 5Step-by-step explanation:
Slope - intercept formula: y = mx + b, where m- slope, b- y-intercept
1. Points are:
(2, -4) and (4, -2)Slope is:
m = (y2 - y1)/(x2 - x1) m = (-2 - (-4))/(4 - 2) = 2/2 = 1y-intercept is - 6 as per graph
Then the formula is
y = x - 62. Points are:
(0,5 ) and (4, 1)Slope is:
m = (1 - 5)/(4 - 0) = -4/4 = -1y-intercept is 5 as per point
Then the formula is
y = -x + 53. Points are:
(-3, 1), (-1, -3)Slope is
m = (3 - 1)/(-1 -(-3)) = 2/2 = 1y-intercept is -5 as per graph
Then the formula is
y = x - 5ILL GIVE BRAINLIEST. HELP ASAP. What is the greatest common factor in the two terms of the expression 3x - 2y?

Miamor wanted to make note cards by cutting pieces of paper in half.
Before starting she got seven more pieces to use. When she was done she
had 28 half pieces of paper. With how many full pieces did she start?
Answer: 14 pieces
Step-by-step explanation:
Let the number of pieces of paper she had at first be x.
Before starting she got seven more pieces to use. This can be written as:
= x + 7
When she was done she had 28 half pieces of paper. This can then be written as:
x + 7 = (28 × 1/2)
x + 7 = 14
x = 14 - 7
x = 7
Since x = 7, she started with:
= x + 7
= 7 + 7
= 14 pieces
A TV was bought for $18,950 and old at a loss of $4780.Find the selling price
Answer:
$23729.19 ( approx )
Step-by-step explanation:
Cost price = $ 18950
Loss = $ 4780
Loss% = 4780/18950 * 100 = 25.22%
Selling Price = 18950 (100+25.22)/100
= $23729.19 ( approx )

If f(x)=4^x-8 and g(x) =5x+6, find (f+g)(x)
Answer:
C
Step-by-step explanation:
(f + g)(x) = f(x) + g(x), then
f(x) + g(x)
= [tex]4^{x}[/tex] - 8 + 5x + 6 ← collect like terms
= [tex]4^{x}[/tex] + 5x - 2 → C

Benjamin's age is 6 years less than twice Lucas's age. If Benjamin is 12 years old, how old is Lucas? Choose the answer below that is a viable solution to this problem
We can express Benjamin's age with x, we can express Luca's age as y.
x-6=2y
So, if x=12
2y=6
y=3
Therfore, Lucas is 3 years old
