Answer:  10.6

6.3-4.15=2.15

8.45-6.3=2.15

so 8.45+2.15=10.6

Given ΔABC, AB = BC = AC . Area of ΔABC = 25 sqrt3 /4 cm. Find the perimeter of ΔABC.
zubka84 [21]
This is an equilateral triangle of height a√3/2 where a is the side length. So the area is ½a.a√3/2=a²√3/4.
So a²=25 and a=5cm. Therefore the perimeter is 3a=15cm.

Find the values of x and y.
nirvana33 [79]

Answer:

x=15.75 y=59

Step-by-step explanation:

In total there is 360 degrees. We know y is 59 so we will replace it with that.

59+59=118. 360-118=242. 242/2=121. 29+29=58. So we can subtract that to equal 63. Now 63=4x. We can divide so 2x=31.5. x=15.75.

Therefore, 15.75=x and 59=y

I hope this helped ^^.

Tell whether the given value is a solution of the inequality.<br> 5x - 17 &gt; 62; x = 13
andrezito [222]

Answer:

the given value x=13 is not a solution of the inequality

Step-by-step explanation:

we first need to solve this inequality (can treat the inequality like a normal equation to solve it)

5x-17 > 62

5x > 79

x>(79/5)

keep in mind that (79/5)=15.8

so x needs to be bigger than 15.8 in order to satisfy this inequality.

since 13<15.8 when x=13 it does not satisfy the inequality

therefore the given value x=13 is not a solution of the inequality

josephine is taking a college course, and her professor bases the course grade on the average of 2 tests taken in the semester.
mihalych1998 [28]

Averaging formula:

A=sum of n values / n

Substitute the variables,

c is the average,

a and b are the test scores

∴

c=\frac{a+b}{2}

rearrange for b

2c=a+b

2c-a=b
