Answer:

z = 8/3

Step-by-step explanation:

10- 3/4z = 8

Subtract 10 from each side

10-10- 3/4z = 8-10

-3/4z = -2

Multiply each side by -4/3

-3/4z * -4/3 = -2 *4/3

z = 8/3

I know it isn’t congruent but how do I explain the reasoning? help ?
nadya68 [22]
They are congruent because the angles are all the same for the one on the left the angles are 79° 43° and 58° and the triangle on the right the angles are 79° 43° and 58° you can say they are confident because of AA (Angle Angle) theorem which means that 2 angles are congruent which means both of the triangles are congruent.

Answer:

12 sapphires

Step-by-step explanation:

Let's call the number of sapphires x. This means the number of rubies is the total number of gems minus x, or 17-x.

# of Sapphires: x

# of Rubies:17-x

A sapphire is worth 5 (gold coins) each, and a ruby is worth 8.

We also know the total amount of money is 100 coins, so

5*x+8*(17-x)=100

5x+136-8x=100

-3x=-36

x=12

Remember:

# of Sapphires: x

# of Rubies:17-x

...so Lara found 12 sapphires and 17-12=5 rubies.

ASHA 777 [7]

Answer:

So using the same formula that we came from the last question

335.80 +3.65c = 803

We find for C by making C the subject of the formula

3.65c = 803 - 335.80

c = (803 - 335.80) \div 3.65

We now evaluate

c = 467.20 \div 3.65

c = 128

Therefore the class need to sel 128 candles to make 803 dollars
