Answer:
Step-by-step explanation:
The equation has one solution.
6(x+2)=5(x+7)
6x+12=5x+35
6x+12-5x=35
6x-5x=35-12
x=23
Therefore, the equation has ONE solution.
Use mental math to find the difference.

StartFraction 12 kilometers Over 1 EndFraction times StartFraction 0.62 miles Over 1 kilometer EndFraction times StartFraction 5280 feet Over 1 mile EndFraction = 392,832 feet
Sila put a wrong number in her calculator when multiplying the numerators.
Sila’s first fraction should be StartFraction 1 kilometer Over 0.62 miles EndFraction.
Sila’s last fraction should be StartFraction 1 mile Over 5280 feet EndFraction.
Sila forgot to divide by 0.62.
Answer:
A
Step-by-step explanation:
Sila put a wrong number in her calculator
Sila jogged 12 kilometers today and wants to know how far she traveled in feet. What error did Sila make while converting from kilometers to feet ? The correct answer is Option a) Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction times Start Fraction 5280 feet Over 1 mile End Fraction = 392,832 feet.
Sila's mistake can be identified in her conversion calculation. She first needs to convert kilometers to miles and then miles to feet. Let's break down the process step by step:
1. Kilometers to Miles:
Start by converting kilometers to miles.
There are 0.62 miles in 1 kilometer.
So, the first fraction is correct:
Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction.
2. Miles to Feet:
Next, convert miles to feet.
There are 5280 feet in 1 mile. Sila's calculation is incorrect at this step. The correct fraction to use here is Start Fraction 5280 feet Over 1 mile End Fraction.
Now, let's put it all together:
- Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction times Start Fraction 5280 feet Over 1 mile End Fraction
Multiply the fractions step by step:
- 12 kilometers * 0.62 miles/kilometer * 5280 feet/mile
- This simplifies to 392,832 feet.
So, Sila's error lies in not using the correct conversion factors for both kilometers to miles and miles to feet.
The correct conversion factors should be applied in sequence, leading to the final answer of 392,832 feet traveled.

Step-by-step explanation:
First find out what the ratio of tulips and roses is for each garden.
Ben: 40÷(4+1) = 8 so 8×4=32 and 8×1= 8
Ina: 40÷(2+5) =5.7 so 2×5.7=11.4 and 5×5.7= 28.6
Use these numbers accordingly.

Which number sentence represents the Associative Property of Addition?
22 + 3 = 25
22 + 3 = 25
0 + 90 = 90
0 + 90 = 90
18 + 7 = 7 + 18
18 + 7 = 7 + 18
4 + (1 + 11) = (4 + 1) + 11
According to the Associative property of Addition, when 3 or more numbers are added, the result (sum) remains the same even if the numbers are grouped in a different way. Here, grouping is done with the help of brackets.
This can be expressed as, a + (b + c) = (a + b) + c.
So, according to this the answer is 4 + (1 + 11) = (4 + 1) + 11.
Hope my answer helps you✌️

I need help with Part A and B
Answer:
Part A) 700 Snack Bags
Part B) [$]1225.00
Step-by-step explanation:
Pretzels and cheese puffs make up 30% (0.30) of the sales which means 210 is 30% of the total bags they sold. You could set up a ratio like this where 1 represents 100%:
210/.30 = x/1
If solved out, you find there are 700 bags total and you can check it by finding that 210 is 30% of 700.

Answer:
okay sorry but its roofs, not rooves but the answer is
Step-by-step explanation:
2 3/5 divided by 3 1/2 which equals 13/5 divided by 7/2
13/5 times 2/7, which equals 26/35. This stands as 26/35 box of nails per roof. Altogether you get 5.94, which you would have to round to about 6 boxes.

What is the equation of this graphed line?
Enter your answer in slope-intercept form in the box.
Answer:
y = 2x + 2
Step-by-step explanation:
As we know, slope intercept is: y = mx + b
m is slope and b is the y-intercept.
Looking at this problem, we can see that the line crosses the y-axis at positive 2, so that is our y-intercept. For the slope, take a point like the y-intercept, and see how many squares is has to go up before it reaches the next square to the right. In this problem the line goes up 2 squares in the time it takes to go to the right 1. So the slope is y over x, or 2 over 1, or just 2.

Answer:
-9
Step-by-step explanation:
27 divided by 9 equals 3 and the ^2 is 3x3 Which equals 9 and then the negative comes
Answer:
-9
Step-by-step explanation:
In this, you should use PEMDAS, parentheses, exponents, multiplication, division, addition, subtraction. It is the order of solving any equation. The first thing you should start with is the parentheses. -27/9 is -3. Since exponents come next, you would do -3 x -3, which equals 9. After that, all that is left is a negative sign being multiplied to 9 (which is in the parentheses still. The negative sign times 9 equals -9. Therefore, your answer is -9. You could check through just in case, but I hope its correct. Also, if you don't mind, could you mark brainliest? I would really appreciate it :D
Jolon used the slope-intercept form to write the equation of a line with slope 3 that passes through the point (5, –2). His work is shown below.
Step 1: Negative 2 = 3 (5) + b
Step 2: negative 2 = 15 + b
Step 3: Negative 2 + 15 = 15 + 15 + b
Step 4: Negative 13 = b
Step 5: y = 3x – 13
Analyze the steps. In which step did the Jolon make an error?
Answer:
step 3
Step-by-step explanation:
He should have subtracted 15 instead off adding 15. this would have gotten rid of the fifteen on the right side and left him with -17=b. Instead, he would have added 15 and gotten 13=30+b. That threw off the rest of the equation. The rest of the equation is wrong. b should equal -17
the slope-intercept equations should be y=3x-17

Mrs. Stephan took her children to pick out pumpkins. Cater picked out a pumpkin priced $20, and Isabel picked out a pumpkin priced $13. How much did Mrs. Stephan pay for both pumpkins, including 7% sales tax?
Answer:
$35.31
Step-by-step explanation:
(20+13) x (1+0.07) = 35.31
You add the price of both pumpkins together to get the price of the pumpkins before tax. Then you multiply it by (1 + 0.07) because 1 is the regular price plus the sales tax which is a percent that can be converted to decimal to 0.07. You multiply these together and get 35.31
Answer:
$35.31
Step-by-step explanation:
(20+13) x (1+0.07)
