Help solve for r algebra

Mathematics
1 answer:
bija089 [108]3 years ago
6 0

Answer:

\frac{20}{7}

Step-by-step explanation:

Multiply both sides by 7 to get rid of the denominator on the Right Side (RS). Do the same for the left side (LS) by multiplying both sides by 5 to get:

7r=4(5)

Simplify: 7r=20

Divide both sides of the equation by 7 to get: r=\frac{20}{7}

Interpreting Points on Graphs of Proportional Relationships
HACTEHA [7]

There are the following conclusions:

Not true

  1. The pumpkin grew to a weight of 3 ounces in 18 weeks.
  2. The quotient 3 / 18 equals the growth rate of the pumpkin in ounces per week.

Cannot be determined

  1. Each crate can hold 18 pumpkins.

True

  1. In 3 weeks, the pumpkin grew to a weight of 18 ounces.
  2. The pumpkin grew at a rate of 6 ounces per one week.

<h3>How to interpret graphs of proportional relationships</h3>

The graph shows the graph of proportional relationship, in which the weight of a pumpkin, in ounces, is directly proportional to time, in weeks. Then:

y ∝ x

y = k · x

Where k is the constant of proportionality, in ounces per week.

The point (x, y) = (3, 18) indicates that a pumpkin reaches a weight of 18 ounces after 3 weeks and the constant of proportionality is equal 6 ounces per week.

Then, we have the following conclusions:

Not true

  1. The pumpkin grew to a weight of 3 ounces in 18 weeks.
  2. The quotient 3 / 18 equals the growth rate of the pumpkin in ounces per week.

Cannot be determined

  1. Each crate can hold 18 pumpkins.

True

  1. In 3 weeks, the pumpkin grew to a weight of 18 ounces.
  2. The pumpkin grew at a rate of 6 ounces per one week.

Solve for x and explain?
zhannawk [14.2K]

Answer:

x = 7

Step-by-step explanation:

When 2 secants are drawn from an external point to a circle.

The product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is

5(5 + x) = 6(6 + 4) ← distribute and simplify both sides

25 + 5x = 6 × 10

25 + 5x = 60 ( subtract 25 from both sides )

5x = 35 ( divide both sides by 5 )

x = 7

Which expression is equivalent to the expression shown ? 2 (x + 5) +3 (x2 - 5x +13)
Gnesinka [82]
\text{Use the distributive property:}\\\\a(b+c)=ab+ac

2(x+5)+3(x^2-5x+13)=(2)(x)+(2)(5)+(3)(x^2)-(3)(5x)+(3)(13)\\\\=2x+10+3x^2-15x+39=3x^2-13x+49
