Can any one help me with this! Please look at the picture below just the circled numbers!!

ArbitrLikvidat [17]

You are right to circle both 10 or 12. Neither can be solved without knowing something about the x values in 10 and the x value of the smaller base in 12.

A first alloy contains x pounds of 55% silver. It is mixed with a second alloy containing 30% silver to make 60 pounds of an all

Ann [662]

Answer:

"24 pounds" is the appropriate answer.

Step-by-step explanation:

According to the question, the equation will be:

⇒ $x+y=60$ ...(equation 1)

or,

⇒ $\frac{55}{100}x+\frac{30}{100}y=\frac{40}{100}\times 60$

$55x+30y=2400$ ...(equation 2)

Now,

By multiplying (equation 1) by 55 and (equation 2) by 1, we get

⇒ $55x+55y=3300$ ...(equation 3)

⇒ $55x+30y=2400$ ...(equation 4)

From equation 3 and 4, we get

⇒ $25y=900$

$y=\frac{900}{25}$

$=36$

By putting the values of "y" in equation 1, we get

⇒ $x=60-36$

$=24$

Thus the value of x be "24 pounds".

Given: ∆ABC, AB = BC, m∠1<90°. Perimeter of ∆ABC = 25. Difference between two sides is 4. Find: AB, BC, AC. Can someone help

goldfiish [28.3K]

Answer:

AB = 7, BC = 7 and AC = 11

Step-by-step explanation:

Let AB = BC = a and CA = b

Now, given that the perimeter of the triangle is 25.

So, 2a + b = 25 ............ (1)

And 4 is the difference between the two unequal sides.

Hence, b - a = 4 .............. (2)

⇒ 2b - 2a = 8 ........... (3)

Now, solving equations (1) and (3) we get, 3b = 25 + 8 = 33

⇒ b = 11

Hence, from equation (2) we get a = b - 4 = 7

Therefore, AB = 7, BC = 7 and AC = 11 (Answer)
