Answer:
x = -20.6
Step-by-step explanation:
Step 1: −5x − 25 − 25 = 78 − 25
Should be
Step 1: -5x-25+25=78+25
Step 2: -5x=103
Step 3: Divide both sides by -5: x = -20.6
This is a simple Pythagorean Theorem problem. 7 is the hypotenuse so you would do c^2-a^2=b^2. In this case 7^2-2^2=b^2. 7^2 is 49 and 2^2 is 4 so you have 49-4=b^2. 49-4 is 45. The square root of 45 is 6.70. So x=6.70
Answer:
15%
Step-by-step explanation:
40=100%
20=50%
4=10%
2=5%
10%+5%=15%
4+2=6
Answer:66
Step-by-step explanation:
The first thing we should know is that a kite has two pairs of adjacent congruent sides, so to find the value of x we are going to set the equations equal to each other. The value of x is 4. After, plugging the value of x into the equations the measure of both angles is 33. Angle TUV is made up of angles TUW, and VUW because of the measure of angle TUV is 66.
10x-7=5x+13
5x=20
x=4
10(4)-7=33
5(4)+13=33
The answer would be A) 5%. You can solve this by dividing 135$ by three years to get 45. then divide 45 by 900 to get 0.05 which is 5% in decimal form.
