Tresset [83]

Answer:

594 rpm

Step-by-step explanation:

Two gears will have the same linear speed, so:

v₁ = v₂

ω₁ r₁ = ω₂ r₂

(316 rpm) (79) = ω (42)

ω ≈ 594 rpm

26÷2 as a repeated subtraction

Sever21 [200]

Answer:

13, but see image for "repeated subtraction" representation

Step-by-step explanation:

Division can be represented as repeated subtraction. Begin with the dividend, 26, in this case. Subtract 2 (the divisor) over and over again and count how many times it can be subtracted. This result from counting is the quotient (answer to a division) See image.

(-28-32r-x+ 1)(x-2)

Reil [10]

Answer:

−25x+54−32rx+64r−x^2

Step-by-step explanation:

(−28−32r−x+1)(x−2)

Add −28 and 1 to get −27.

(−27−32r−x)(x−2)

Apply the distributive property by multiplying each term of −27−32r−x by each term of x−2.

−27x+54−32rx+64r−x^2+2x

Combine −27x and 2x to get −25x.

−25x+54−32rx+64r−x^2

Answer:

f=4

Step-by-step explanation:

Priya Tried to solve the equation below step-by-step:

$\qquad\begin{aligned} \dfrac f{0.25}&=16\\ \dfrac{f}{0.25} \cdot0.25&=16\cdot0.25&\green{\text{Step } 1}\\ f&=4&\blue{\text{Step } 2}\\\end{aligned}$

The steps are correct and indeed f=4.
