A farmer sells 7.1 kilograms of apples and pears at the farmer's market. 4 5 of this weight is apples, and the rest is pears. Ho
zheka24 [161]

Answer:

2.6Kg

Step-by-step explanation:

Let the weight of apples be x and that of pears be y .

The farmer sold 7.1 kg of apples and pears .

4.5 of the 7.1kg is apples

That’s

x + y = 7.1kg

4.5kg + y = 7.1kg

Subtract 4.5kg from both sides

4.5kg - 4.5kg + y = 7.1kg - 4.5kg

y = 2.6 kg

The farmer sold 2.6kg of pears at the market

Can someone please give me the (Answers) to this? ... please ...<br><br> I need help….
bezimeni [28]

Answer:

see explanation

Step-by-step explanation:

2 chords intersecting inside a circle , then the product of the parts of one chord is equal to the product of the parts of the other chord.

6

BE × ED = AE × CE , that is

10 × 3x = 12(2x + 1) ← distribute parenthesis by 12

30x = 24x + 12 ( subtract 24x from both sides )

6x = 12 ( divide both sides by 6 )

x = 2

then

ED = 3X = 3(2) = 6

7

RJ × JP = SJ × JQ , that is

6 × 3x = 4(4x + 1) ← distribute parenthesis by 4

18x = 16x + 4 ( subtract 16x from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

then

RP = RJ + JP = 6 + 3x = 6 + 3(2) = 6 + 6 = 12

koban [17]

Answer:

-4/3

Step-by-step explanation:

-\frac{1}{2} = \frac{3}{8}y\\-\frac{1}{2} \cdot \frac{8}{3} = \frac{3}{8}y \cdot \frac{8}{3} \\\\-\frac{8}{6} = y\\\boxed{y = -\frac{4}{3}.}
