Answer:

4 feet

Step-by-step explanation:

Let x be the height of the tower when finished.

We have been given that Priya takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 of the height of the tower she wants to build.

This means that 5/8 of x equals 2 and 1/2. Let us represent this information in an equation.

5/8*x=2 and 1/2

Let us convert our given mixed fraction into an improper fraction.

5/8*x=5/2

Let us multiply both sides of our equation by 8/5.

8/5*5/8*x=5/2*8/5

x=8/2

x=4

Two angles are supplementary. The larger angle is 33 degrees more than 6 times the smaller angle. Find the measure of each angle

noname [10]

Sum of two angles that are supplementary = 180°

Let the smaller angle be = x

$Let \: the \: smaller \: angle \: be \: = \: x$

$then \: the \: larger \: angle \: = 6x + 33$

<h3>Their sum :</h3>

$x + 6x + 33 = 180$

$7x + 33 = 180$

$7x = 180 - 33$

$7x = 147$

$x = \frac{147}{7}$

$x = 21$

Using this let us find the measures of the smaller angle and bigger angle .

$smaller \: angle \: = x = 21°$

$larger \: angle \: = 6x + 33 = 6 \times 21 + 33 = 126 + 33 = 159°$

∴ The measure of the two angles are = 21° and 159° .

If an integer m is divisible by both 10 and 12, then it must also be divisible by which of the following?

Murrr4er [49]

Answer:

Step-by-step explanation:

an integer m is divisible by both 10 and 12

Lets write the prime factor for each number

the prime factor for 10 is 5,2

the prime factor for 12 is 3,2,2

Now take the product of the prime factors that are not in common and also in common $5 \cdot 3 \cdot 2 \fdot 2= 60$

60 is divisible by 20

so answer is 20

2y+5x=4<br> please answer

marshall27 [118]

Answer:x=x=

−2

Step-by-step explanation:

Let's solve for x.

2y+5x=4

Step 1: Add -2y to both sides.

5x+2y+−2y=4+−2y

5x=−2y+4

Step 2: Divide both sides by 5.

−2y+4

−2

Answer:

−2
