How do I find the measure of these two supplementary angles using algebra?

Mathematics
1 answer:

Answer:

70 and 110

Step-by-step explanation:

The two angles add to 180 degrees since they form a straight line

2x+10 +3x+20 =180

5x+30 = 180

Subtract 30 from each side

5x+30-30 =180-30

5x = 150

Divide by 5

5x/5 =180/5

x = 30

The left angle is 2x+10 = 2*30+10 = 60+10 =70

The right angle is 3x+20 = 3*30 +20 = 90+20 = 110

Christina goes to the market with $50. She buys one papaya for $8 and spends the rest of the money on bananas. Each banana costs
velikii [3]
Christina can buy 7 bananas because one papaya is 8 dollars and then you do 50-8=42 and then 42/6 which equals 7.

Billy can only buy one pair of jeans. The reason is that jeans are 35 bucks and he has already spent  55 dollars on a hat and jacket and that leaves him with 35 bucks left so 35-35 equals zero!

Omar is putting 5 liters of water in two goldfish bowls. He spills 200 milliliters of water and divides the remaining water even
DedPeter [7]

Answer:

a) 0.2 L

b) 4800 ml

c) 2400 ml

Step-by-step explanation:

Total volume of water = 5 litres

Since 1000 milliliters make 1 L

5L = 5000 ml

a) litres of water spilt = 200/1000 = 0.2 L

b) milliliters of water remaining = 5000 - 200 = 4800 ml

c) since it was expressly stated in the question that the remaining water was divided evenly; 4800/2 = 2400 ml in each bowl
