<u>Solve for x:</u>

88 + x - 88 = 180 - 88

x = 92

lisov135 [29]

Answer:

The regular costs 11 dollars each while the deluxe cost 23 each.

$12,400 is invested, part at 6% and the rest at 5%. If the interest earned from the amount invested at 6% exceeds the interest e
tester [92]

Answer:  $10881.81 is invested at 6% and $1518.18 is invested at 5%.

Step-by-step explanation:

Since we have given that

Amount invested = $12400

Rate of interest for first part = 6%

Rate of interest for second part = 5%

Let the amount invested for 6% be 'x'.

Let the amount invested for 5% be 'y'

According to question, we get that

0.06x-0.05y=577\\\\x+y=12400\\\\\implies x=12400-y

So, it becomes,

0.06(12400-y)-0.05y=577\\\\744-0.06y-0.05y=577\\\\-0.11y=577-744\\\\-0.11y=-167\\\\y=\dfrac{167}{0.11}\\\\y=1518.18

x=12400-y=12400-1518.18=$10881.81

Hence, $10881.81 is invested at 6% and $1518.18 is invested at 5%.

Use the figure to find x
Butoxors [25]

Answer:

<u>The</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>x</u><u> </u><u>is</u><u> </u>\frac{7\sqrt{6}}{2}

Solution given:

AB=7

BD=x

<BAC=60°

<DBC=45°

In right angled triangle ABC

Tan 60°=opposite/adjacent

Tan 60°=BC/AB

Substitute value

\sqrt{3}=\frac{BC}{7}

BC=7\sqrt{3}

again

In right angled triangle BCD

Using Cos angle

Cos 45=adjacent/hypotenuse

Cos45°=BD/BC

Substituting value

\frac{\sqrt{2}}{2}=\frac{x}{7\sqrt{3}}

Doing criss cross multiplication

\frac{\sqrt{2}}{2}*7\sqrt{3}=x

x=\frac{7\sqrt{6}}{2}
