There was 45 markers originally in each box.
How do we know?
Well, 3*x = 15*3 + 90 = 45 + 90 = 135
Divide both of the sides by 3
X = 135/3 = 45
Therefore, that’s how we know that there was 45 markers originally.

7/10 - 1/2 whats the answer
Serjik [45]
To find the answer, we can use expansion to turn the fraction’s denominator to be the same:

1/2
= 1×5 / 2×5
=5/10

We can then proceed to find the answer:

7/10 - 5/10
= 2/10
= 1/5

Therefore the answer is 1/5.

Hope it helps!

Slope of a parallel line with the points (7,-5) and (-5,7)
VLD [36.1K]

Answer: Negative 1  The slope of parallel lines is the same.

The attachment shows two such lines, given coordinates labeled.

Step-by-step explanation:

Find the slope of the line passing through the given points.

 rise/run  

Rise is the difference in y-values  7-(-5)  = 12

Run is the difference between x-values  -5 - 7  = - 12

The Slope is 12/-12   simplify:

slope = -1

Find all solutions for a triangle with c=70 c=24 and a=25
Slav-nsk [51]

Answer:

see the attachments for the two solutions

Step-by-step explanation:

When the given angle is opposite the shorter of the given sides, there will generally be two solutions. The exception is the case where the triangle is a right triangle (the ratio of the given sides is equal to the sine of the given angle). If the given angle is opposite the longer of the given sides, there is only one solution.

When a side and its opposite angle are given, as here, the law of sines can be used to solve the triangle(s). When the given angle is included between two given sides, the law of cosines can be used to solve the (one) triangle.

___

Here, the law of sines can be used to solve the triangle:

A = arcsin(a/c·sin(C)) = arcsin(25/24·sin(70°)) = 78.19° or 101.81°

B = 180° -70° -A = 31.81° or 8.19°

b = 24·sin(B)/sin(70°) = 13.46 or 3.64
