Answer:

x>-4

Step-by-step explanation:

Answer: post image of the math Sheri walked 15/16 of a mile to school and then 7/8 of a mile to the library. Estimate how far Sheri walked in total.

Step-by-step explanation:

1.8125 miles

just added 15/16 + 7/8

1.8125 miles

15/16 + 7/8

Answer:

Simplify:

7x - 3 ≥ (8 - 2x) * 9

7x - 3 ≥ 72 - 18x

7x + 18x ≥ 72 + 3

25x ≥ 75

x ≥ 75 / 25

x ≥ 3

Answer: it helps by making the question 10 times easier

Step-by-step explanation: because 4 and 6 both have the variable X they are like terms and can be added to each other unlike 30 it doesn’t have a variable meaning 4x or 6x cannot combine with 30 because it doesn’t have the variable X. Moving on 4x+6x is 10x as you add the number but X stays the same and so 10x=30 so you divided both sides by 10 because inverse operations and you get x=3 then after you import that into the question 4(3)+6(3)=30 which is the same as 12+18=30 which is true 30=30

Answer: Answering all under step by step

Step-by-step explanation:

for a point just put a dot

for a line just draw a line with arrows pointing on both sides

for a line segment draw a line with two dots on the ends

for a ray draw a line with one side with an arrow and the other a dot

the difference between line and line segment is that a line is extended in both directions infinitely but a line segment has two endpoints

the difference between line segment and a ray is that a line segment has two endpoints and stops at the points while a ray goes on forever in one direction

for parallel lines just draw two lines on top of each other both going on forever

perpendicular line cross each other only once and never again. u can just make them look like a cross

draw a triangle on the top left dot. then draw a box around any two points and the line in between. and then draw a circle around either of the corners.

Answer:

168°

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle, which is k, in this case.

m∠J = 78 and m∠L = 90° so the measure of exterior angle to ∠K:

78 + 90 = 168°

Answer:

Negative 7/40 or - 7/40

Step-by-step explanation:

Answer: -7/40

Step-by-step explanation:

first multiply the two negatives so it becomes (2-|-1/4+2 x 3/5|) /(-6)

then that becomes (2- | -1/4 + 6/5 | ) /(-6)
the sum of those two fractions become (2- | 19/20|) /(-6)

(2-19/20)/(-6)

2 - 19/20 /-6

21/20 /-6

multiple both by a negative so that become -21/20 /6

multiply the 6 with the recirocal so it becomes 1/6

-21/20 and 1/6 turn into -7/20 and 1/2 by canceling out with the greatest common factor of 3

now multiply both and u get -7/40

Answer:

first one

Step-by-step explanation:

The correct option is B i.e., triangle RST ~ triangle UVW;5/6

Given,

In the Polygons,

In DRST, RS = 10  , RT = 15 and mDR = 32

In DUVW, UV = 12 , UW = 18 and mDU = 32.

To check the similarity and give the similarity ratio.

Now, According to the question:

Analysis the above given:

Here, RS/ UV = RT/UW = 5/6

AND, ∠R = ∠V = 32°

and, there is two sides are equal and one angle is equal.

Then, By postulate SAS two polygons are congruent.

Hence, The correct option is B i.e., triangle RST ~ triangle UVW;5/6

Answer:

*name* is 10 years old now and brother is 15 years now

In 10 years they would be 20 and 25 respectively

Step-by-step explanation:

Let x = *name*'s age now

let y = brother's age now

The first relationship is that the ratio of their ages now is 2:3 or, in fraction form 2/3

That means x/y = 2/3

Cross multiply => 3x = 2y =>

3x - 2y = 0   [1]

10 years from now x would become x + 10 years, y would become y + 10 years and the new ratio is 4/5

So (x + 10)/(y+10 = 4/5

Cross-multiply

5(x + 10) = 4(y + 10)

5x + 50 = 4y + 40

Subtract 4y from both sides

5x + 50 -4y = 40

and subtract 50 from both sides:

5x - 4y = 40 - 50

5x -4y = -10  [2]

Eliminate y terms by multiplying [1] by 2 and subtracting [1] from that

[1] x 2

=> 2(3x - 2y) = 2 x 0

=> 6x - 4y = 0  [3]

[3] - [2]

6x - 4y - (5x -4y) = 0 - (-10)

6x - 4y -5x + 4y = 10

x = 10

Using equation [1] we get

x/y = 2/3

=> 10/y = 2/3

10 x 3/2 = y

5 x 3 = y

y = 15

So their ages are 10 and 15 now.

In 10 years they would be 20 and 25

If the ratios change we would have a different set of equations to solve for

For example if the current ratio is 1/3

Then we would get x/y = 1/3

or 3x - y = 0  [4]

and if 10 years from now the ratio is 3/5 then

(x + 10)/(y + 10) = 3/5

=> 5(x+10) = 3(y + 10)

=> 5x + 50 = 3y + 30

=> 5x - 3y = -20  [5]

And we would solve these equations to get x and y in a similar mannter

FYI the answers would be
x = 5, y = 15

Answer:

Loren's work is not correct because you are originally dividing by 61.4. In the division problem, they moved the decimal point to the right and did the same to the problem inside of the division symbol to make it easier. After you would finish doing all the division, you would count the amount of spaces behind the decimal point and put the decimal point that many spaces in the answer. Loren forgot to count the decimal point that you moved right at the beginning. To summarize, Loren forgot the decimal point you moved at the beginning and Maddie is correct.
