Answer:

x = 7

Step-by-step explanation:

The final step in this "two-step" linear equation is to multiply both sides by the inverse of the coefficient of x.

$\dfrac{4}{3}(x)=\dfrac{28}{3}\qquad\text{given}\\\\\dfrac{3}{4}\cdot\dfrac{4}{3}(x) = \dfrac{3}{4}\cdot \dfrac{28}{3}\qquad\text{multiply by $\dfrac{3}{4}$}\\\\x=\dfrac{28}{4}=7$

The solution is x = 7.

In triangle △ABC, ∠ABC=90°, BH is an altitude. Find the missing lengths. AB=9, and AC=12, find HC.

pickupchik [31]

Answer:

Step-by-step explanation:

It is given that in △ABC, ∠ABC=90°, BH is an altitude and AB=9 and AC=12, thus using the Pythagoras theorem in △ABC, we get

$(AC)^{2}=(AB)^{2}+(BC)^{2}$

$(12)^{2}=(9)^2+(BC)^2$

$144=81+(BC)^2$

$(BC)^2=63$

$BC=\sqrt{63}$

Now, From ΔABC and ΔHBC, we have

∠ABC=∠BHC(each90)

∠ACB=∠HCB (Common)

By AA similarity, ΔABC is similar to ΔHBC.

Thus, using the similarity condition, we get

$\frac{HC}{BC}=\frac{BC}{AC}$

$\frac{HC}{\sqrt{63}}=\frac{\sqrt{63}}{12}$

$HC=\frac{63}{12}=\frac{21}{4}$

Dennis and Ivy share some sweets between them in the ratio 7:4 Dennis got 42 sweets. How many does ivy get

MrRa [10]

Answer:

$Ivy = 24$

Step-by-step explanation:

Given

$Dennis : Ivy = 7 : 4$

Required

Determine the amount of sweet Ivy gets when Dennis = 42

We have:

$Dennis : Ivy = 7 : 4$ and

$Dennis = 42$

Substitute 42 for Dennis in $Dennis : Ivy = 7 : 4$

$42 : Ivy = 7 : 4$

Convert to fraction

$\frac{42}{Ivy} = \frac{7}{4}$

Cross Multiply:

$Ivy * 7 = 42 * 4$

Divide through by 7

$\frac{Ivy * 7}{7} = \frac{42 * 4}{7}$

$Ivy = \frac{42 * 4}{7}$

$Ivy = 6* 4$

$Ivy = 24$
