Answer:
Step-by-step explanation:
14.3 + 21.1 + x = 50
35.4 + x = 50
x = 50 - 35.4
x = 14.6 <=== she biked 14.6 miles on the 3rd day
Answer:
x = 49.5°
Step-by-step explanation:
∠ABC = 90°
∠CBD = 45%∠ABC
∠CBD = 0.45(90)
∠CBD = 40.5°
x = ∠ABC - ∠CBD
x = 90 - 40.5
<u>x = 49.5°</u>
I dont know if this will be correct but i think she is gonna spend about 92 or 93 dollars on her mother
Answer:
x=50
Step-by-step explanation:
The total number of angles in a quadrilateral is 360.
<em>set the expressions you have as equal to 360</em>
(x+10)+3x+2x+x = 360
<em>collect the x terms together</em>
7X + 10 = 360
<em>subtract the 10 to get just "x"s on one side</em>
7X = 350
<em>divide by 7 to get X alone</em>
x = 50
