Write an equivalent expression for 4(a+5)

Drupady [299]

$\huge \boxed{4a+20}$

We can do this using the distributive property, which states that $a(b+c)=ab+ac$ .

Distribute the $4$ to the $a$ and the $5$ . $4a+4(5)$

Multiply. $\displaystyle \boxed{4a+20}$

In the diagram of circle R, m FGH is 50. what is mFEH

garri49 [273]

Options

130°
230°
260°
310°

Answer:

(B) $m\angle FEH=230^\circ$

Step-by-step explanation:

We know that the External Angle = Half the Difference of the Two Arcs

Therefore:

Since FGH is the exterior angle and FEH and FH are the two arcs, then:

$\dfrac12 (\angle FEH-\angle FH)=50^\circ\\\\\angle FEH- \angle FH=100^\circ$

Also:

$\angle FEH+ \angle FH=360^\circ$

Adding the two equations, we have:

$\angle FEH- \angle FH+(\angle FEH+ \angle FH)=360^\circ+100^\circ\\2\angle FEH=460^\circ\\$Divide both sides by 2\\Therefore\\m\angle FEH=230^\circ$

A rental car company charges $31.35 per day to rent a car and $0.15 for every mile

Tju [1.3M]

31.35d + 0.15(275) </= 280

Step-by-step explanation:

(Daily cost x number of days) + (mileage cost x number of miles) is less than or equal to $280.

If they ask you to solve it next:

31.35d + 0.15(275) </= 280

31.35d + 41.25 </= 280

31.35d </= 238.75

d </= 7.615629998

Round it down to 7 full days

17. If13=xy-5 and y = 6, what is the value of x? (A) 0 (B) 3 (C) 6 (D) 8

ludmilkaskok [199]

Answer:

Option B: 3

Step-by-step explanation:

#1: Substitute in 6 for $y$ and 3 for $x$ : $13=(3)(6)-5$

#2: Multiply 3 and 6: $13=18-5$

#3: Evaluate the equation: $13=18-5$ → $13=13$

#4: Check if the solution is equal: $13=13$ ✓

$x$ is equal to 3 (Option B).
