Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.Josiah has punch c

love history [14]

Let x be the number of weeks; therefore, the two linear equations are

$\begin{gathered} T=2+7x \\ \text{and} \\ C=11+4x \end{gathered}$

Where T stands for the punches on the tea punch card and C for the punches on the coffee punch card.

Solving by substitution. Set T=C, then

$\begin{gathered} T=C \\ \Rightarrow2+7x=11+4x \\ \Rightarrow3x=9 \\ \Rightarrow x=\frac{9}{3}=3 \\ \Rightarrow x=3 \end{gathered}$

Thus, substitute the value of x=3 into the first equation,

$\begin{gathered} x=3 \\ \Rightarrow T=2+7\cdot3=23 \\ \Rightarrow T=23 \end{gathered}$

Thus, after 3 weeks, Josiah will have the same number of punches on each card, and he will have 23 punches on each card.

Find the value of x. Round your answer to the nearest tenth. 10 19° x

kvasek [131]

Answer:

x ≈ 9.5

Step-by-step explanation:

using the cosine ratio in the right triangle

cos19° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{10}$ ( multiply both sides by 10 )

10 × cos19° = x , then

x ≈ 9.5 ( to the nearest tenth )
