LKJ= 360
L and J are congruent
360-64-36= 260
X=260-80
260-80 =180
X=180
Y=x^2 + 16 is the correct answer to your question
To find the exact answer based on the last step, "
", you must use PEMDAS (attached image below)
Thus the answer is <u>59</u>.
Hope that helps!
<u>all expression represent how much Judith spent.</u>
Answer:
<u>Question:</u>
Judith's grandmother paid her x dollars a week to mow the lawn during the summer.
Judith decided to save some of her money and spend the rest. For the first 4 weeks, Judith put $10 per week into savings. For the next 8 weeks, she put $15 per week into savings.
<u>Solution given:</u>
Judith's grandmother paid her x dollars a week
<u>it means Judith's income per week is x.</u>
Judith decided to save some of her money and spend the rest.
For the first 4 weeks, Judith put $10 per week into savings.
<u>it mathematical expression it is expressed as:</u>
<u>4(x-$10)</u>
again
For the next 8 weeks, she put $15 per week into savings.
<u>it mathematical expression it is expressed as:</u>
<u>8(x-$15)</u>
<u>now,</u>
<u>Judith's </u> have
<u>4(x-$10)+8(x-$15) </u>it represent 1st expression.
solving above equation
<u>(4x-$40)+(8x-$120) </u>represents 4t h expression.
<u>(4x+8x)-($40+$120)</u> represents 2nd expression.
12x-$160 represents 3rd expression.
