Let the number of apples be x and that of pears be y, then:
0.64x + 0.45y = 5.26 . . . (1)
0.32x + 0.39y = 3.62 . . . (2)
(2) x 2 => 0.64x + 0.78y = 7.24 . . . (3)
(1) - (3) => -0.33y = -1.98
y = -1.98 / -0.33 = 6
From (2), 0.32x + 0.39(6) = 3.62
0.32x = 3.62 - 2.34 = 1.28
x = 1.28 / 0.32 = 4

The model y=1.8x−76.9 y=1.8x−76.9 represents the relationship between the temperature (°F) and the number of ice cream cones sold. Using the model, approximate the number of ice cream cones sold when it is 85°F. Round your answer to the nearest whole number.
Answers
Answer:
76 ice cream cones
Step-by-step explanation:
Given the model : y=1.8x−76.9 ;
Which shows the relationship between temperature and number of ice cream cones sold ;
Using the model, the predicted number of ice cream cones sold when temperature is 85°F
Hence, x = 85
Putting x = 85 in the model and solve for y
y = 1.8(85) −76.9
y = 153 - 76.9
y = 76.1
Hence, the number of ice cream cones sold is 76

ANSWER NOW PLEASE: Tom is having his car repaired. The cost of the parts is $260
and 4 hours of work are required. Tom needs to keep the
entire cost of the repair under $400. Which inequality
expresses the relationship between hourly cost (x), parts,
and the $400 limit?
Answers
Answer:
260 + 4x < 400
Step-by-step explanation:
To make our inequality, let's list out the separate costs we have, all of which combined should be less than 400.
First, we have the cost for the parts, which is $260. The other cost we have is the hourly rate for the work. The repair will take a certain amount of money for every hour worked. The rate must be low enough that it doesn't exceed $400 when combined with the $260 from the parts.
To construct our inequality, we can begin with the estalished $260.
Then, add to this the hourly rate, (x) times the number of hours worked, 4.
So we have-
260 + 4x
The total of this cost must be less than $400 dollars, so we will use the less than ( < ) sign in front of the 400.
260 + 4x < 400
The answer is 260 + 4x < 400. I hope this was helpful :] Good luck ^^
Find the missing terms in the arithmetic sequence 1, __, __, __, 29,...
Answers
9514 1404 393
Answer:
8, 15, 22
Step-by-step explanation:
The sequence has ...
a1 = 1
a5 = 29
__
The generic formula for an arithmetic sequence is ...
an = a1 +d(n -1)
Filling in the known information, we can find d:
29 = 1 + d(5 -1)
28/4 = d = 7
The terms of the sequence have a common difference of 7, so each is 7 more than the one before. The first five terms are ...
1, 8, 15, 22, 29
The missing terms are 8, 15, 22.

Answer:
C is at -17 on the number line
Step-by-step explanation:
point A is at -7, point B is at 3, that makes them 10 units away from each other, Point C is the same distance away from A just like B is but in the opposite direction. -7 -10=-17, therefor C is at -17
