I’m confused on the question.?
The ratio of angles is 1 : 2.6 or 5 : 13.
The sum of the angles of a linear pair is 180°. The above ratio tells us that the smaller angle is ...
... 5/(5+13) · 180° = 50°
Then the larger angle is 180° - 50° = 130°
The two angles are 50° and 130°.
Answer:
a = 4,
b = 12
c = 10
d = 15
Step-by-step explanation:
Since the product of each column is equal, therefore,
b*5 = 60
b = 60 ÷ 5 = 12
c*6 = 60
c = 60 ÷ 6 = 10
Since the sum of each column are equal, therefore,
12 + 10 + a = 5 + 6 + d
22 + a = 11 + d
Think of a number you can add to 22, and another number you can add to 11, which will make both sides equal. Add both numbers, whenmultiplied together should give you 60.
Factors of 60 are:
(a, d)
(1, 60) => 22 + a = 11 + d => 22+1 = 11+60 (incorrect)
(2, 30) => 22 + a = 11 + d => 22+2 = 11+30 (incorrect)
(3, 20) => 22 + a = 11 + d => 22+3 = 21+20 (incorrect)
(4, 15) => 22 + a = 11 + d => 22+4 = 11+15 => 26 = 26 [CORRECT]
(5, 12) => 22 + a = 11 + d => 22+5 = 11+12 (incorrect)
(6, 10) => 22 + a = 11 + d => 22+6 = 11+10 (incorrect)
Therefore,
a = 4,
d = 15
Answer:
v= -2
Step-by-step explanation:
10+2v=−6(3v+5)
Step 1: Simplify both sides of the equation.
10+2v=−6(3v+5)10+2v=(−6)(3v)+(−6)(5)(Distribute)10+2v=−18v+−302v+10=−18v−30Step 2:
Add 18v to both sides.
2v+10+18v=−18v−30+18v20v+10=−30
Step 3:
Subtract 10 from both sides
.20v+10−10=−30−1020v=−40
Step 4:
Divide both sides by 20.20v20=−4020v=−2
Answer:v=−2
