WHAT DOES THIS MEAN I DONT UNDERSTAND

Mathematics
1 answer:
Art [367]3 years ago
3 0

Answer:

the goal is to try and get x alone. For the 1st problem, x=3.

Step-by-step explanation:

3x + 1 = 10      Subtract 1 both sides to cancel out the 1 on the left side. 10-1 = 9

3x = 9             To get x alone here, Divide 3 on both sides. 9/3 = 3

x = 3                Now x is alone, which means x = 3.

This is right because if you plug x with 3, the sum = 10.

(3*3) + 1 =10

9 + 1 = 10

So, that's how you know 3 is the right answer.

Nora and Lila are reading the same novel for book club. Nora is on page 128 and plans to read 8 pages per day until the next clu
kicyunya [14]

Answer:

- They will be on the same page after 6.5 days or 6\frac{1}{2} days.

- They will be on page 180.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

You know that Nora plans to read 8 pages per day until the next club meeting and she is on page 128.

With this information you can write the following equation of the line in Slope-Intercept form to represent the number of the page "y" she will be on after "x" days:

y=8x+128

Know that Lila is on page 102 and plans to read 12 pages per day until the next club meeting, you can write this linear equation that represent the number of the page "y" she will be on after "x" days:

y=12x+102

Since they will be on the same page after "x" days, make both equations equal and solve for "x":

8x+128=12x+102\\\\26=4x\\\\x=6.5

Substitute that value into any original equation the same page they will be on after 6.5 days (or 6\frac{1}{2} days):

y=12(6.5)+102\\\\y=180

Mario has 7 cups of milk. A one batch recipe for pancakes calls for 2/3 cup milk. To see how many batches he could make Mario fi
Inessa [10]

Mario's mistake is made when doing reciprocal.

7 / (2/3) =

I cannot divide by 2/3, but if I do reciprocal, I can multiply by 3/2. The seven comes first, so it should not be flipped.

Mario's mistake was when he flipped the 7 (or 7/1) to 1/7.

PLS HELP ME PLS I WILL MARK BRAINLIEST PLS
Vesnalui [34]

Answer:

AB = 25

Step-by-step explanation:

First things first, we know that these triangles are similar. Now let's find BC using the Pythagorean Theorem. BC = 5\sqrt5, this side is similar to the 5 side of the smaller triangle. That means each side of the larger triangle \sqrt5 times larger than the corresponding side on the small triangle. That means AB is \sqrt5 times larger than BC as well. So multiply BC by \sqrt5 get us the answer.
