1. A recipe calls for 1 1/2 cups of flour, 3/4 cup of white sugar, and 1/3 cup of brown sugar. The recipe makes 6 servings.

MrRa [10]

A.) you take the number r of servings and divide it by the number of cups of flour which would be 0.25 cups of flour or 1/4 cups of flour per serving

B.) You add 0.75 (amount of white sugar) and add 0.33 (amount of brown sugar) which is 1.08 then divide it by 6 and you will get 0.18 cups per serving

C.) You take the initial amount of cups you got from part A and multiply it by because the number of servings doesn't change the amount you use per serving and you would get 2 and 1/4 cups of flour for the 9 servings.

Which expression is the factorization of x2 + 10x + 21?

LiRa [457]

<h2>Solution:</h2>

Equation: x² + 10x + 21

Step 1: Find two numbers that can add up to 10 and be multiplied to 21. We have: 7 & 3, in the sense that 7+3=10, and 7×3=21. Replacing 10 with 7+3, the equation is now → x² + 7x + 3x + 21

Step 2: Get the new equation bracketed → (x² + 7x) (+3x + 21)

Step 3: Use 'x' in the equation. For the first part, we have 'x'. x² = x × x so, bring out one x out side the bracket, divide 7x by = 7 → x (x +7). Do the same for the second part by dividing 21 by 3 = 7, and then bringing out 3 from the bracket → 3 (x + 7).

Bringing everything together, we have: x(x+7) +3(x+7) → (x+3) (x+7)

<h3>Final answer:</h3>

(x+3) (x+7)

Mary is traveling to Ecuador for her summer vacation. She looks at a map of the path of her flight. Her plane leaves from Florid

arlik [135]

Answer:

The coordinates of Ecuador is (7,8)

Step-by-step explanation:

Represent Ecuador with E, Panama with P and Florida with F

Given

F(x1,y1) = (5,16)

P(x,y) = (6,12)

Required

Determine the coordinates of E(x2,y2)

From the question, we understand that P is located at the midpoint of E and F.

Using midpoint formula, we have

(x,y) = (½(x1 + x2), ½(y1 + y2))

Substitute values for x,y,x1 and y2;

This gives

(6,12) = (½(5 + x2), ½(16 + y2))

By direct comparison of expression on both sides

½(5 + x2) = 6

½(16 + y2) = 12

Solving for the first equation

Multiply both sides by 2

5 + x2 = 6 * 2

5 + x2 = 12

Make x2 the subject of formula

x2 = 12 - 5

x2 = 7

Solving the second equation

Multiply both sides by 2

16 + y2 = 12 * 2

16 + y2 = 24

Make y2 the subject of formula

y2 = 24 - 16

y2 = 8

Hence, the coordinate of Ecuador is (7,8)

Jana And Jordan had 23 oranges Jana had 7 fewer oranges than Jordan how many oranges did each girl have

Solnce55 [7]

Answer:

Jana had 8 oranges, and Jordan had 15 oranges.

Step-by-step explanation:

First, identify what you know:

1) In total, Jana and Jordan had 23 oranges.

2) Jana had 7 less oranges than Jordan.

We can create a formula, where x equals the number of oranges Jana has.

23 = x + (x + 7)

16 = x + x (subtracted 7 from both sides)

x = 8 (divided both sides by 2)

So, now we know Jana had 8 oranges, which is 7 less than Jordan.

8 + 7 = ?

? = 15

Jana had 8 oranges, while Jordan had 15, for a total of 23 oranges.
