Answer:

x < 1 and x > -2

Step-by-step explanation:

5x - 1 < 4 and 3x + 5 > x + 1

Step 1.) Transfer the -1 over by the 4 by adding it because you use the opposite symple when its transfered.

5x < 5 and 3x + 5 > x + 1

Step 2.) Divide 5 by 5 to get the variable alone

x < 1 and 3x + 5 > x + 1

Step 3.) Subtract x from 3x which gives 2x and subtract 5 from 1 which gives -4

x < 1 and 2x > -4

Srep 5.) Divide -4 by 2 to get the variable alone and you get -2

x < 1 and x > -2

Answer: perpendicular

Step-by-step explanation: You can do this (of course, you have to know the equations of the pairs of lines under consideration);

For each equation, put in form y = mx + b and compare their slopes (values of m).

If the m's are equal, the two lines are parallel;

if the product of the two m's equals -1, the two lines are perpendicular.

Answer:

x=86

Step-by-step explanation:

The angles of a triangle add up to 180 degrees.

we can use this to get a problem: x+52+42=180

simplify to get:

x+94=180

subtract 94 from each side to get your answer:

x=86

5/9×3/10= 15/90 simplification is 1/6

the correct is 1/6

Answer:

The 4th answer is correct

Step-by-step explanation:

[tex]\frac{5}{9} *\frac{3}{10} \\\\[/tex]

[tex]\frac{5*3}{9*10}[/tex]

[tex]\frac{15}{90}[/tex]

Now you can make the answer as the simplest form divide both sides by 15

[tex]\frac{15}{90} =\frac{1}{6}[/tex]

ANSWER IS,

[tex]\frac{1}{6}[/tex]

Answer:

whats the question?

due to my knowledge its 75 because it is.

Step-by-step explanation:

first I thought the angles at Q and P are right angles (90 degrees). but the last part tells me they are not.

so, all the "perpendicular" answers are out.

answer 1 and 2 are all correct but I would pick 2, because it had the most detail that's true.

and since these 2 lines are parallel, the must have the same angles with the crossing line.

therefore, when the angle RQS is 75 degrees, then the angle TPU is also 75 degrees.

Answer:

Larry will need 6 and 2/3 cups of cherries.

Step-by-step explanation:

since one pie takes 1 1/3 cups, you would want to multiply that by 5 to see how many cups it will take for 5 pies. When you do this, you get a mixed number of 20/3 which simplifies to 6 2/3. I hope this helps.

Answer:

Step-by-step explanation:

Answer:

x = 10        m∠3 = 74

Step-by-step explanation:

(10x + 6) + (7x + 4) = 180 degrees

17x + 10 = 180

17x = 170

x = 10

check answer

(10(10) + 6) + (7(10) + 4) = 180

106 + 74 = 180

180 = 180

true!

angle 5 is vertical angles with 3, so they are congruent

use same equation as 5

7(10) + 4

70 + 4

74 :)

According to the calculations made, 410 gumballs will be needed to fill the box.

Since you are trying to figure out how many gumballs you need to fill a 7.3 x 5.0 x 9.4 rectangular box for Halloween, and each gumball has a radius of 1/2 in, if the packing density for spheres is 5/8 of the volume will be filled with gumballs while the rest will be air how many gumballs will be needed, to determine this amount the following calculation must be performed:

Therefore, 410 gumballs will be needed to fill the box.
