Answer:

  1.  D. The water will be about 50°C. (54.8 (rounded up) is 50.)
  2.  C. 23; the amount the temperature increases each minute.

Step-by-step explanation:

x = 6 (6 minutes)

5.3 x 6 + 23 = 54.8

5.3 x 6 = 31.8

31.8 + 23 = 54.48

2.  C.  23: the amount of the temperature increased each minute.

8 divide by 1 1/4 KCF
Diano4ka-milaya [45]

Answer:

32/5

Step-by-step explanation:

K=Keep the first Fraction (You can rewrite 8 as 8/1 for when you multiply across.)

C=Change the Division Sign to a Multiplication Sign

F=Flip the Second Fraction

First, rewrite 1 1/4 as 5/4 (A mixed number can be changed to a fraction by multiplying the outside whole number by the denominator or bottom number of the fraction, then add the new rewritten whole number and the original fractional piece. In this case you would multiply the outside 1 by the bottom 4 and add it to the original 1/4. 4/4+1/4=5/4)

Second, Flip 5/4 to 4/5 and change your equation so it now reads: 8/1 x 4/5

Third, use simple fraction multiplication and multiply across to get 8/1 x 4/5=32/5

Examine the system of equations.
SashulF [63]

Answer:

y=11

Step-by-step explanation:

Solve the system by substitution by setting the equations equal to each other.

y = 5x+6

y = x+10

It becomes 5x+6 = x+10. Solve for x using inverse operations.

5x+6 = x+10

4x+6 = 10

4x = 4

x=1

Substitute x=1 into one equation to find y.

y = x+10

y = 1 +10

y=11
