−5x − 25 = 78
Step 1: −5x − 25 − 25 = 78 − 25 WRONG
- 5x - 25 = 78
- 5x - 25 + 25 = 78 + 25
- 5x = 103
x = - 103/5
x = - 20,6
Answer:
Step-by-step explanation:
−5x − 25 = 78
Step 1: −5x − 25 − 25 = 78 − 25 <== this is where the error was made.
Step 2: −5x = 53
Step 3: = −5x/−5=53/−5
Step 4: x = −53/5
Right steps:
−5x − 25 = 78
Step 1: −5x − 25 + 25 = 78 + 25
Step 2: −5x = 103
Step 3: −5x/−5 = 103/−5
Step 4: x = 103
Step 1 was where the error was, because she subtracted 15 from both sides instead of adding 15, so they cancelled out.
Hope this helps!

Find the function value
f(1) if f(x) = x + 3
Answer:
f(1) = 4
Step-by-step explanation:
Given:
[tex]\displaystyle \large{f(x)=x+3}[/tex]
Find f(1) by substituting x = 1 in the function f(x):
[tex]\displaystyle \large{f(1)=1+3}\\\displaystyle \large{f(1)=4}[/tex]
Hence, the solution is f(1) = 4

Lucy was watching her brother's team play baseball in the town playoffs. A man selling raffle tickets posed a challenging question to the crowd. He asked if anyone could figure out the area of the shaded half of the baseball field. Help Lucy figure out the answer by using the drawing below. please explain how you got your answer!
Step-by-step explanation:
Area is Base x Height right?
so, the base of the triangle would be 90 ft and the height would be 90 ft!
So 90 x 90 = 8,100 ft!!
This is how I think, so it may be wrong, but this is how I do it!
answer:
a=1/2×b×h
a=1/2x90×90
a=45×90
a=4,050 ft.
in simpler terms....
90×90=8100
this is the area of the ENTIRE FIELD so to find half divide by two 8100÷2=4,050.
4,050 ft.
GOOD LUCK!!!

A store sells grass seed in small bags and large bags. The small bags have 7 pounds of seed for $27.93 and the large bags have 20 pounds of seed for $66.98. Which type of bag is the better buy? Explain your reasoning.
Answer:
The 20 pound bag is a better by for only $66.98
Step-by-step explanation:
The large bag is better because the small bag is $27.93 for 7 pounds 7x3=21,so 3x27.93=83.79 is $16.81 more than the cost for the large bag

The Pythagorean theorem states that a² + b² = c² for a right triangle with leg lengths, a and b, and hypotenuse length, c.
The hypotenuse of a right triangle is 5 units long and has the points (4, 0) and (0, 3) as end points. One of the legs has length 4.
Use the Point and Segment tools to draw a right triangle that demonstrates the other leg length is 3.
Step-by-step explanation:
They have already done the math for you, you just need to draw a line with the length of 3 units, so it would look like this:

Step-by-step explanation:
Given:
QR= 45 mm
RS= 15, (1/3 of QR is 15).
QT is 90 mm
We must find ST.
Equation:
Use Segment Addition Postulate Theroem,
QR+RS+ST=QT

Sofia's family took a road trip to Mount Rushmore. Sofia slept through the last 65% of the trip. If the total length of the trip was 840 miles, how many miles had they travelled when Sofia fell asleep?
Answer:
546
Step-by-step explanation:
Sofia slept 546 miles and was awake for 45% which is 294 of the miles.
You can find this by finding 1%, and that would be 8.4. (You get 1% from dividing 100 from the 100% number.) Then you multiply it by 65 so now you get 546.
If the total length of the trip was 840 miles, then Sofia had traveled 294 miles before she fell asleep.
Given that,
If Sofia slept through the last 65% of the trip and the total length of the trip was 840 miles,
then she stayed awake for the first 100% - 65% = 35% of the trip.
Here, we have to calculate the distance she traveled before falling asleep, we can use the percentage of the total distance:
Distance traveled by Sofia = 35% of 840 miles
Distance traveled by Sofia = 0.35 * 840
Distance traveled by Sofia = 294 miles
So, Sofia had traveled 294 miles before she fell asleep.

Donovan eats 2 granola bars and drinks 1 glass of orange juice for breakfast every day. The price of a granola bar is B dollars and the price of a glass of orange juice is J dollars. The expression 7(2B+J) describes how much Donovan spends on breakfast in one week. Match each amount in the situation with the expression that represents it.
Answer:
B. Amount Donovan spends on granola bars each day.
Step-by-step explanation:
B is the price of a granola bar, so 2B is the price of two granola bars. Donovan eats 2 granola bars each day, so if he buys them, he spends 2B per day on granola bars.

V= volumer = radiusYou have been given the radius of 4.5 cm, so all you have to do is plug this information into the equation and solve!
V = [tex]\frac{4}{3}[/tex]π(4.5)²

Answer:
[tex] \frac{3}{2} [/tex]
Keep in mind:
constant of proportionality = the slope
Step-by-Step Explanation:
We can see that the point is at (4, 6). In order to find the slope, we need to find a different point that intercepts a whole number point on the graph.
We have two valid points; (2, 3) and (6, 9). One way to find the slope is to subtract y-coordinate 1 (6) and y-coordinate 2 (3 or 9).
Then, subtract x-coordinate 1 (4) and x-coordinate 2 (2 or 6).
[tex] \frac{6 - 3}{4 - 2} = \frac{3}{2} [/tex]
OR
[tex] \frac{6 - 9}{4 - 6} = \frac{ - 3}{ - 2} = \frac{3}{2} [/tex]
