Answer:
11x + 20y + 10
Step-by-step explanation:
When there is a - in front of an expression in parentheses, change the sing of each term in the expression. So it would be (8x + 20y) + 3x + 10. Then combine like terms.
Answer:
y = 1.6x
Step-by-step explanation:
y is the total amount/pounds of almonds that Lark bought. x is the amount that Tessa bought. 3/5 is the same as 0.6. If we multiplied Tessa's amount by 0.6 it would decrease by 2/5 so we have to add 1 to make it 1.6. To find how much Lark bought multiply 1.6 and Tessa's amount.
-3 is your answer, for every 3 y-values, it increases 1 x-value. so that means our answer is -3.
She was unable to salvage 4.8% of the total number of samples. If she was able to salvage 12 of the 24 improperly stored samples, then she was unable to salvage 12 of them. Divide the number that was not salvaged (12) by the total number of samples (250), then multiply by 100 to get the percentage.
Answer:
Using a bar graph where one bar has a length of 2.4 and one bar has a length of 1.8
Step-by-step explanation:
You use a bar graph to compare things between different groups, so it is the most appropriate one to use.
You use a pie chart to compare parts of a whole, so it would not be appropriate.
The graph should represent the relative sizes of the two values (24:18 or 1.33:1). Using a square or a cube would distort the relationship. The relative area of the squares would be 1.77:1 and that of the cubes would be 2.37:1.
