<span>So, x+15 + 2x = 90 </span><span>
<span>Therefore 3x = 90 - 15 = 75 </span>
<span>and so x=25. </span>
<span>So the smaller angles are x+15 = 40 degrees and
2x=50 degrees. </span>
<span>So the larger one is 50 degrees.</span></span>
Answer:
1). (x - 4 = 13)
2). (r + 17 = 51)
3). (7/9x =28)
4). (2/3x = 2)
5). { 3(x-2) = -9 }
6). (x -1.75 = 8.85)
7). Natalie buys organic almonds priced at $77 from the grocery store. How much did
she pay the cashier, if she received $23 in change?
Step-by-step explanation:
1. add 4 on both sides and it will be x=17
2. subtract 17 on both sides and it will be x= 34
3. multiply 9/7 on both sides and it will be x= 257/7 then you divide 257 by 7 then the final answer will be x= 36
4. multiply 3/2 on both sides and it will be x=6/2 then you divide 6 from 2 and the finial answer will be x= 3
5. you will distribute 3 into x and 2 and you will be 3x-6=-9 then you will add 6 on both sides so you will get 3x=3 and then divide 3 on both side so you will get x=1
6. add 1.75 on both sides so x= 10.6
7. the equation will be 23 +x = 77 so first you will subtract 23 on both sides and x will equal 54 so Natalie paid $54
Answer:
Let width of rectangle be x cm.
3x+x+3x+x=39
8x=39
x=39÷8
=39/8
=4/7/8
3x=39/8×3
=117/8
=14/5/8
Hence, length=14/5/8cm while width=4/7/8cm.
