ruben is buying bricks for a project. he knows that 5 bricks weigh 26 1/4. he wants to know the weight of 24 bricks

Phoenix [80]

Answer:

the weight of 24 bricks is :

$124\frac{4}{5}$

Step-by-step explanation:

$26\frac{1}{4} =26+\frac{1}{4} =\frac{26\times 4}{4} +\frac{1}{4} =\frac{105}{4}$

It is clear that there is a proportional relationship between the number of bricks and their weights then :

$\frac{26\frac{1}{4} }{5} =\frac{x}{24} \Longrightarrow \frac{\left( \frac{105}{4} \right) }{5} =\frac{x}{24} \Longrightarrow \frac{26}{5} =\frac{x}{24}$

$\Longrightarrow x=\frac{26\times 24}{5} =\frac{624}{5} =124\frac{4}{5}$

Solve the following 2 equation.<br>I will Make Brainliest

Levart [38]

Answer:

d. $x = 10$

e. $x=\sqrt[3]{\dfrac{15}{4}}$

Step-by-step explanation:

I've typed up my workings in MS Word and attached them (as it's very difficult to type this in the Brainly equation editor).

I've used the product, quotient and power log laws.

Product: $log_a(x)+log_a(y)=log_a(xy)$

Quotient: $log_a(x)-log_a(y)=log_a(\dfrac{x}{y})$

Power: $p\log_a(x)=log_a(x^p)$

Simplify in fraction form<br> 60a+64≥80a−92

lukranit [14]

Answer:

a≤39/5

Step-by-steep explanation:

60a+64≥80a−92

Step 1: Subtract 80a from both sides.

60a+64≥80a−92

-80a -80a

−20a+64≥−92

Step 2: Subtract 64 from both sides.

−20a+64≥−92

-64 -64

−20a≥−156

Step 3: Divide both sides by -20.

−20a≥−156

a≤39/5
