So we want to know how to write the inequality for Beth's jogging. The total number of miles Beth plans to jog cant go over 12, and she has already jogged for 3 miles, then she needs to jog for another m miles. This can be written mathematically like: 3 + m < 12. In other words: 3 miles + m miles Beth still plans to jog cant go over 12 miles.
Answer:
Break down the problem into these 2 equations.
a+6=3a+2
a+6=3a+2
a+6=2a
a+6=2a
Solve the 1st equation: a+6=3a+2a+6=3a+2.
a=2
a=2
Solve the 2nd equation: a+6=2aa+6=2a.
a=6
a=6
Collect all solutions.
a=2,6
a=2,6
Step-by-step explanation:
Answer:
1.6
Step-by-step explanation:
4-(-4)=-8
2-(-3)=-5
-8 divided by -5 =
1.6
Answer:
30
Step-by-step explanation:
since the 2 sides are congruent, the two angles are congruent, so
75+75+ x= 180
150+x=180
x=30
Answer:
UV=142
Step-by-step explanation:
21x-13=10x+31
+13 +13
21x=10x+44
-10x=-10x
11x=44
÷11 ÷11
x=4
now substitute 4 in place of x (only have to solve one)
21(4)-13= 71
now multiply your answer by 2
71×2=142
