Answer:
Angle 1=66
Step-by-step explanation:
Step 1, solve for angle 2
<2+123=180 degrees
Angle 2=57 degrees
Step 2, solve for angle 1
Since this is an isosceles triangle, to solve for angle 1, the equation is 2(57)+x=180
Angle 1=66 degrees
Answer
y= 4
Step-by-step explanation:
6x-7y=22
6x(-1)-7y=22
-6-7y=22
-7y=22+6
-7y=28
y=-4
Answer:
#1. 2 and 16
#2. 12
Step-by-step explanation:
Answer: Bob has 62 cards.
All has 124 cards.
Jane has 186 cards
Step-by-step explanation:
Let x represent the number of cards that Bob has.
Al has twice as many cards as Bob. It means that the number of cards that All has is 2x.
Jane has three times as many cards as Bob. It means that the number of cards that Jane has is 3x.
Together, they have 372 cards. It means that
x + 2x + 3x = 372
6x = 372
x = 372/6
x = 62
The number of cards that Al has is
2 × 62 = 124
The number of cards that Jane has is
3 × 62 = 186
