Just add all of the same variables. x+1/2x+4x all have the same variable, and 4 is it's own variable. Answer simplified is 5.5x+4.
Answer:
11/12
Step-by-step explanation:
10/24 + 12/24 = 22/24
22/24 = 11/12
Answer:
1.3, 1.6, 1.9
Step-by-step explanation:
Add .3 each time
x - 24 = 3 (-1) x
x - 24 = -3x
-24 = -4x
x = 6
Step-by-step explanation:
<em>BD</em> = 56
Step-by-step explanation:
Step 1: In rectangle, the diagonals are congruent and bisect each other.
So, <em>AC</em> = <em>BD</em>
⇒<em>AG</em> + <em>GC</em> = <em>BG</em> + <em>GD</em>
⇒<em>AG</em> + <em>AG</em> = <em>GD</em> + <em>GD</em>
⇒ 2<em>AG</em> = 2<em>GD</em>
⇒<em>AG</em> = <em>GD</em>
⇒ –7<em>j </em>+ 7 = 5<em>j</em> + 43
⇒–7<em>j</em> – 5<em>j</em> = 43 – 7
⇒–12<em>j</em> = 36
⇒<em>j</em> = –3
Step 2: <em>BD</em> = 2<em>DG</em>
<em>BD</em> = 2(5<em>j</em> + 43)
= 2(5 (–3) + 43)
= 2(–15 + 43)
= 2 × 28
= 56
Hence, <em>BD</em> = 56.
