Answers
Answer:
The final answer is
-283/8
Step-by-step explanation:
Given the expression
5/(-1.5+9.5) + 0.4 (7+11) / -0.2
To solve this problem we need to break down its component in steps
Step one
First Let's solve the items in the bracket
5/8+ 0.4 (18) / -0.2
Secondly let's open up the bracket
5/8+7. 2/-0.2
Step two :
We can still solve for the second fraction by Dividing it accordingly
=5/8+(-36)
=5/8-36
Solving the fraction we have
Lcm= 8
=5-288/8
=-283/8

N = H - 8
S = 15
S = N + 4
Plug in 15 for 'S':
15 = N + 4
11 = N
N = H - 8
11 = H - 8
Add 8 to both sides:
19 = H

What is inequality?
In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
A bratwurst costs $4.50 at a softballgame.
And you have a total of $18 to spend.
Let n be the number of bratwursts, you can buy.
So, the inequality that represents the situation is,
4.5n ≤ 18
Divide the inequality by 4.5 into both sides,
we get,
n ≤ 18/4.5
n ≤ 4
n = 4.
Therefore, the number of bratwursts is 4.

Answer:
The average number of pizzas sold in one night if no coupons are issued is 43.
Step-by-step explanation:
In the scatter plot the average number of pizzas sold is represented on x and number of coupons issued is represented on y.
The trend line of this linear model is
So, when no coupons are issued then the value of x becomes 0, then putting the value of x in the equation,
Therefore, the average number of pizzas sold in one night if no coupons are issued is 43.
Answer:
The correct answer option C.
Step-by-step explanation:
Let x be the number of coupons issued.

Step-by-step explanation:
1 1/4 (or 1.25) cups to 20 servings = 1 gallon (16 cups) to x servings
1.25 16
--------- = -------- cross multiply
20 x
(1.25)(x) = (20)(16)
1.25x = 320
x = 320/1.25
x = 256 servings <===
