Answer:

a) 69

b) 69

Step-by-step explanation:

Since 69 and x are alternate interior angles, they must be congruent, and therefore x must equal 69 degrees. Similarly, since y and 111 must be supplementary, it must also be equal to 180-111=69 degrees. Hope this helps!

X= 69 degrees as it is an alternate angle to ‘69 degrees’. Whilst y=69 degrees too, as it is supplementary(180-111=69)
Therefore, x=69. Y=69. x=y

Lisa is 10 cm taller than her friend ian. Ian is 14 cm taller than jim. Every month, their heights increase by 2 cm. In 7 months

koban [17]

Answer: Ian's height = x+14 = 69+14 = 83 cm

Explanation :

Let the height of Jim be x

Let the height of Ian be x+4

Let the height of Lisa be x+4+10=x+14

Since their heights increase by 2cm every months

so after 7 months ,

Jim's height = x+14

Ian's height= x+4+14=x+18

Lisa's height= x+14+14=x+28

According to question,

Sum of Ian's and Jim's height = 170cm

$x+18+x+14 = 170\\2x+32 =170\\2x =170-32\\2x = 138$

⇒x = $\frac{138}{2}$

⇒ x= 69cm

∴ Ian's height = x+14 = 69+14 = 83 cm

Charli bought 2 3/4 pounds of pears for 0.76 per pound and 2 3/4 pounds of grapes for 1.40 per pound. how much money in dollars

MArishka [77]

Answer:

$Total = \$5.94$ ---- in dollars

$Total = 594\ cents$ ---- in cents

5 dollars 94 cents

Step-by-step explanation:

Given

Pears

$Weight = 2\frac{3}{4}\ lb$

$Amount = \$0.76$ per pound

Grapes

$Weight = 2\frac{3}{4}\ lb$

$Amount = \$1.40$ per pound

Required

Determine the amount paid for the fruit in dollar and cents

First, we need to calculate the amount paid for each fruit.

This is calculated by multiplying the amount per pound by the number of pounds bought.

For Pears:

$Total_{Pears} = 2\frac{3}{4} * \$0.76$

Convert fraction to decimal

$Total_{Pears} = 2.75 * \$0.76$

$Total_{Pears} = \$2.09$

For Grapes

$Total_{Grapes} = 2\frac{3}{4} * \$1.40$

Convert fraction to decimal

$Total_{Grapes} = 2.75 * \$1.40$

$Total_{Grapes} = \$3.85$

Next, we add both amounts together to get the total amount spent in dollars.

$Total = Total_{Pears} + Total_{Grapes}$

$Total = \$2.09 + \$3.85$

$Total = \$5.94$

Multiply by 100 to convert this amount to cents

$Total = 5.94 * 100\ cents$

$Total = 594\ cents$

And it can be represented as dollars and cents as:

5 dollars 94 cents

Ted is saving for a toy. He has no money now, but

sweet-ann [11.9K]

Answer:

4D - 1

Step-by-step explanation:

So, if Ted saves $D for 4 weeks, then this amount will be equal to 4D because multiplication is simply repeated addition. We can imagine this situation as D+D+D+D, for the 4 weeks he is saving. We can simplify this to 4D in the expression.

Next, the question tells us that this will be 1 dollar more than needed. So, if we want to find the cost, we need to subtract that dollar.

Thus, the final expression is 4D - 1 because this represents 1 dollar less than the money he saves for 4 weeks.
