Gabby has entered a cooking contest with 6 rounds. In order to earn a medal, she needs a final average score higher than 75. After the first five rounds, her average score is 78. What must her score be in the sixth (final) round to earn a medal? Show your work and answer in a complete sentence.
Answer:
85
Step-by-step explanation:
We will use the formula
xbar = \sum Xi/N
xbar is the average
N is the number of rounds
\sum Xi is sum of rounds
From the formula:
\sumXi = xbar × N.
If Gabby has entered a cooking contest with 6 rounds and in order to earn a medal, she needs a final average score higher than 75, this means that;
N = 6
xbar = 75+x (since her average needs to be more than 75)
Substitute in the formula
\sumXi = 6(75+x) ....... 1
If after the first five rounds, her average score is 78, then:
At N = 5, xbar = 78
Substitute into the formula
\sumXi = 5(78)
\sumXi = 390..... 2
First we need to get x by equating equation 1 and 2:
6(75+x) = 390
450 + 6x = 390
6x = 390-450
6x = -60
x = -10
Taking x as 10
Since she needs 75+x to earn the medal, substitute x = 10 into the expression:
This means that she will need average score of 75+10 i.e 85 to win the medal
4. An integer between -5 and -6
Answer:
The integers are the whole numbers, both positive and negative. The next integer after 5 is 6, so there is no integer between them. Since 5 and 6 are consecutive numbers, it is not possible to squeeze another integer between them. So, the answer is none.

Erica solved the equation −5x − 25 = 78; her work is shown below. Identify the error and where it was made. (5 points) −5x − 25 = 78 Step 1: −5x − 25 − 25 = 78 − 25 Step 2: −5x = 53 Step 3:negative five times x over negative five = fifty-three over negative five Step 4: x = negative fifty-three over five Group of answer choices Step 1: She should have added 25 to each side. Step 1: She should have divided both sides by −5. Step 3: She should have divided both sides by −5. Step 3: She should have multiplied both sides by −5.

Mangojuicecosts$8.50perquartandbananajuicecosts$6.20perquart.Tyler wants to make a mixture of mange and banana juice that sells for $5.50 per quart. How many quarts "q" of mango juice should he mix with 4 quarts of banana juice to make mango-banana juice at that price? Which equation below represents the situation?
Answer:
There is no possible combination that will result in mango-banana juice that costs $5.50 per quart if its two ingredients cost $8.50 and $6.20 per quart.
Step-by-step explanation:
the equation you need to solve is:
let M = quantity of mango juice
$8.50M + (4 x $6.20) = (4 x $5.50) + $5.50M
$8.50M + $24.80 = $22 + $5.50M
$24.80 - $22 = $5.50M - $8.50M
$2.80 = -$3M
M = $2.80 / -$3 = -0.933 ⇒ the quantity of mango juice cannot be negative

of the total distance. If Charlie drove the rest of the distance, how many miles did Charlie drive?
The distance droved by Charlie is about 38 miles
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
The distance between San Antonio and Houston is 190 miles. Nicholas and Rose each drove 2/5 of the total distance.
Distance droved by Nicholas = Distance droved by rose = (2/5) * 190 = 76 miles
Distance droved by Charlie = 190 - 76 - 76 = 38 miles
The distance droved by Charlie is about 38 miles

PLZZZZ HELP! write the equation in standard form y=3/4x - 4
Answer:
3x-4y = 16
Step-by-step explanation:
The height h (in feet) of an object dropped from a ledge after x seconds can be modeled by h(x)=−16x2+4. The object is dropped again from a different starting height so that it hits the ground 2 seconds later. Write a function g that models the path of the object the second time it is dropped.
Answer:
g(x) = - 16x² + 100
Step-by-step explanation:
Given the model:
First drop:
h(x) = - 16x² + 4
Second drop hits the ground 2 seconds later
Function g(x) to model the second drop:
-16t² + V0t + h0
h(x) = - 16x² + 4
0 = - 16x² + 4
16x² = 4
x² = 4/16
x² = 1/4
x = 1/2
2 seconds later :
X = 1/2 + 2
x = 2.5
0 = - 16(2.5)² + 0 + h0
0 = - 100 + h0
h0 = 100
Hence,
g(x) = - 16x² + 100

Find the values of < and y.
(8x + 7)
5yº
(7y -- 34)
= (2x - 4)^
Answer:
x = 11
y = 17
Step-by-step explanation:
We know that opposite angles (or vertical angles) are equal.
So
8x + 7 = 9x - 4
Subtract 8x from both sides of the equation
8x - 8x + 7 = 9x - 8x - 4
7 = x - 4
Add 4 to both sides of the equation
7 + 4 = x - 4 + 4
11 = x
Looking at the other 2 angles,
5y = 7y - 34
Subtract 7 y from both sides of the equation
5y - 7y = 7y - 7y - 34
-2y = -34
Divide both sides by -2
-2y/-2 = -34/-2
y = 17
Answer:
Step-by-step explanation:
Vertically opposite angles are equal.
8x + 7 = 9x - 4 {Add 4 to both sides}
8x + 7 + 4 = 9x
8x + 11 = 9x {Subtract 8x from both sides}
11 = 9x - 8x
x = 11
7y - 34 = 5y {Add 34 to both sides}
7y = 5y + 34 {Subtract 5y form both sides}
7y - 5y = 34
2y = 34 {Divide both sides by 2
y = 34/2
y =17

Write the point-slope form of the equation of the line that passes through the point (-1,5) and has a slope of -1. Include
your work in your final answer. Type your answer in the box provided to submit your solution.
Answer:
y= - x + 4
Step-by-step explanation:
The point-slope form of the equation of a line is:
y= m ( x - h )+ k
Where m is the slope and (h,k) is a point through which the line passes.
The slope of the line is m=-1 and it passes through (-1,5), thus the equation of the line is:
y=(-1) ( x - (-1) ) + 5
Operating:
y= - ( x + 1 ) + 5
y= - x - 1 + 5
Simplifying:
y= - x + 4
