I need help with this question!!!

Nuetrik [128]

Answer: B. positive 6

Step-by-step explanation: Addomg the positive number to a negative number would turn it to a positive eventually. So u covert your factions to decimals to better see the resemblance. And 1 1/2 is the same as 1.5, and 2 1/10 is the same as 2.1 but it’s easier to deal with decimals. So then just add the positive to the negative sense 1 1/2 is closer to zero. I hope this helps I’m not the best at explaining things

The slope of the line is..?<br> A. -2<br> B. -1<br> C. 1<br> D. 2

Nezavi [6.7K]

Answer:

B, -1

Step-by-step explanation:

on a graph with 2 points (or more) listed, you can count the points from each coordinate to determine slope (which is rise/run also known as y/x)

going from left to right, we start at (1,4) and count down from (1,4) to (3,2), we go down 2 units

going from left toright again, we start from (1,2) (our point we counted down to from (1,4) and count to the left 2 units

we are now at (3,2)

it took us 2 points down (negative) and 2 to the right (positive) to get from (1,4) to (3,2)

using rise/run we have the following:

-2/2 < we can simplify this further by dividing -2 by 2 and getting 1

the answer is B, -1

ANOTHER WAY

another way we can calculate the slope is by the following formula

y2 - y1/ x2- x1

(1,4) is our x1 and y1, while (3,2) is our x2, y2. we plug this into the formula and we get:

y2 - y1 = 2 - 4 = -2

x2 - x1 = 3 - 1 = 2

-2 / 2 = -1

we still have the same answer, and this formula is useful when you dont have a graph to count down from

Gemma and Leah are both jewelry makers. Gemma made 106 beaded necklaces. Leah made 39 more necklaces than Gemma.

weeeeeb [17]

Answer:

Gemma made $34 more than Leah.

Step-by-step explanation:

Gemma made number of beaded necklaces = 106

Leah made 39 more necklaces than Gemma.

Leah made number of beaded necklaces = 106 + 39 = 145

a. There are 104 beads on each necklace.

The total number of beads used altogether

= (106 × 104) + (145 × 104)

= 11,024 + 15,080

= 26,104

b. Gemma sold her 106 necklaces for = $14

Total price of her necklaces = 106 × 14

= $1,484

Leah sold her 145 necklaces for = $10

Total price of her necklaces = 145 × 10

= $1,450

Difference in Gemma and Leah's amount = 1484 - 1450 = $34.00

Therefore, Gemma made $34.00 more money than Leah.
